The following VSC have been added to sems CE:
* vsc_off
* clir
* colr
* dnd
The toggle version of the vsc codes is still NOT added because
reserved for PRO only.
Additionally the code has been reformated to align it with
the PRO version.

If the Content-Length is empty, then it makes no sense
to parse and filter application/sdp body.
Otherwise a parser is going to fail and answer with 488.
Change-Id: I92cdd19319c6f4a4edcfbaeec7bad1be12c8a0b0
Add parsing of Content-Length, for cases
were this length matters (e.g. ct length > 0,
but suddenly there is no SDP body).
Also add a getter for the AmContentType's length.

Reverse inheritence between singleton class and its base.
Change singleton template so that the singleton class doesn't inherit
from its base, but rather that the singelton class inherits from the
singleton template. This removes the need to keep the singleton base
classes separate (with the underscore prefix) plus a `typedef` for the
singleton class, and instead makes the class itself become the
singleton. (The exception being intermediate classes that have multiple
other derived classes, which is only the wheeltimer).
This makes for cleaner typing, but requires use of listing the singleton
template as friend class.
No functional changes.

The destructor is good enough, and it removes ambiguity to the
singleton's own dispose method.
No functional changes.

Rework the payload to be a string instead of the raw char array.
This eliminates cases when we actually need to track that this char array
is indeed null-terminated and deprives us from doing other tricks to
properly maintain this char array.
Also no need to return const of payload anymore, because simply copied
during return. Data protection ensured by not giving a reference to the payload,
modifiable still during the first time setting this payload.
Rework also other users, such as nested call into AmSdp provided `parse()`.
Now `parse()` takes a string, and already in a local scope handles a char array
copy of this given string. This is only because the `parse_sdp_line_ex()` still
requires a refactor to be working with strings instead of char array.
Additionally: move parser helpers of AmSdp to const char pointers,
instead of working on a plain char pointer. This is because the SDP body
parser has been moved from the referenced pointer `char *&`
to the `const char *` pointer. This allows to not have additionally
heap allocated SDP body C-string for parsing purposes.
No functional change.
Change-Id: Ic3ee6c349b62e7e5e0cd4de722f9ed923862a7cb
Preamble: no functional changes.
AmSdp::parse() mixes int values with bool,
what makes the behavior not really clear, not defined
and can lead to the unpredicted result (even though the
compiler *should* actually fix that, but one ought to
not rely on this).
Hence make the parse method only be working with bool values.
Then, reverse the return value so that it's clear
that wrongly parsed is `false`, and good parsed is `true`.
Refactor all users accordingly.
Also rework those users, who indeed need `int` value
be returned, e.g. when having -1.
Do the same thing with the `parse_sdp_line_ex()` helper,
whereas parse() is the only user of it. And also reverse
the interpretation of true/false.
Then, make `parse()` working with a plain `char*`, so not a const.
Because doing a tricks like:
cast `char*` to const (user level) -> cast `const char*` to non-const
in a function (in a old C-like manner), has really no sense.
Refactor everything accordingly.
Other than that, refactor AmMimeBody:
Refactor it to work with a plain `char *` pointer instead of working
with `unsigned char *`, which nowadays has really no sense and
rather is a rudiment of C-like code base coming from the past.
Convert `payload` from `unsigned char*` to `char *` accordingly.
Refactor everything in AmMimeBody implementation accordingly.
Remove rudiment C-like casting everywhere, where possible.
Update `parseMultipart()` to work with a plain `const char *`
instead of `const unsigned char*`
P.S.: leave a list of TODO's for further rework, which
is not directly related to this scope of rework.

When using that, the return value must always
be checked, because the parsing itself can indeed fail.

Set the port in fake SDP answer (to the other side)
coming from the leg, which now replaces the previously
existing one, to the port gotten from the replace INVITE.
Otherwise, if to use the port from the pending transaction
(towards pick-up'er) it confuses rtpengine with a case
when same port talks to himself, and then can later be
used to update the pick-uper's leg once again.

Force the leg being connected instead of the replaced one
to the rtp_relay_mode = RTP_Direct, because otherwise

If the CallLeg isn't SIP relayable, then makes no sense
to relay INVITE to the other leg, otherwise it gets stuck
on the other side.

When this leg being reconnected, is still in progress
of posting remaining events to update the other side
(the reconnect originator), don't consider it as
sip relay ready. Otherwise any INVITE updates coming
to it, will lead to stumbled INVITEs coming to the other leg,
but without a possibility to use it here (because e.g. this
other side never seen 200OK answer even).

We can now use the sets to iterate the bindings in order of their
expiry and exit the loop when we encounter the first one with an expiry
in the future.
Change-Id: I093bea9807b4a432ac965b402394edc43eef5a1f
Add an ordered set of all AorEntry objects, ordered by expire time.
Amend modifier methods to update the set whenever some expire time is
updated or an entry or binding removed.
Change-Id: I2afe5becfa2124dbc8c33b38fe1a3e6d4b8a20d5
Move deletion of bindings into AorHash, similar to how expire times are
set. This makes it possible to manage expiry in a central place.
Change-Id: I76a72881ed202e85fb70e9d8526bac55863d07db
Make AorEntry keep an ordered set of all bindings, ordered by expire
time. This makes it easy to quickly tell when the next binding is set to
expire, and which one. Store iterators to bindings in the set so that
they can be used to directly remove the binding when expired.
Change-Id: Ib63c15d5f6e8990e2f4d237726be54da76194a20
Provide accessor methods. Put the setter into AorHash and require
iterators. All bindings must be in an AorEntry container and all
AorEntry objects must be in the AorHash container. By putting the setter
in AorHash and using iterators we can make sure that the binding is in
the container already and that expiry values are kept consistent.

Provide a proper class for key matching/ordering instead of
hand-crafting a key to be used as index in several places. Use a simple
ordered map instead of the bucket-based approach.

Put all AorEntry objects into a single hash map. Eliminates the need for
AorBucket. Use an unorered hash map for performance. Use lock guards
instead of manual lock/unlock. Remove an unused argument to gbc().
Switch to the full tick cycle length instead of the tick-based one as
there are no more buckets to iterate.

Simplify the little-used RegisterCache alias hash by using the new
hash_map template. Eliminates the need for AliasBucket. Use an unordered
hash map for performance. Use lock guards instead of manual lock/unlock.
Manually `delete` contained objects as our table's .erase() doesn't do
that.

Instead of relying on a short tick duration to make sure the thread
exits when requested, add a dedicated condition flag and variable. Use
AmThread on_stop to set it and wake up the thread. Use the condition
variable's timed wait instead of nanosleep for the ticks.
This somewhat duplicates what other threads are doing, and what
stop_requested() is doing, and should be unified into a single mechanism
provided by AmThread in the future.

Temporarily releasing the lock only to immediately re-acquire it, just
because the called function does a lock/unlock, without re-checking all
data that is protected by the lock, opens the door to subtle race
conditions. Change the semantics of removeRegistration() to require
being called with the lock held. Update handleRegistrationTimer() to
also not release and re-acquire the lock.

Rework the `nbWrite()` function so, that it gets safe
in terms of:
- operating on data written/data remaining integers
- has protection guards for extra big chunks to write at once
Refactor to use size_t/ssize_t instead of primitive int,
where possible (e.g. bytesWritten).
Let the `nbWrite()` use reference instead of pointer
for the bytes written parameter.
Fixes Coverity Scan report:
4. tainted_data_return: Called function write(fd, sp, nToWrite),
and a possible return value may be less than zero.
5. cast_overflow: An assign that casts to a different type,
which might trigger an overflow.
Overflowed integer argument (INTEGER_OVERFLOW)
13. overflow_sink: nToWrite, which might have overflowed,
is passed to write(fd, sp, nToWrite).
7. overflow: The expression nToWrite is considered
to have possibly overflowed.
