As this is only a syntactic sugar there is no difference,
but from the style perspective the project tends to
use C++ style.

Properly select the equal operator based on long instead.
Otherwise it selects the `ValueStruct` as the latest
possible from the variant based `_value` and eventually
it gets stumbled over `[]` operator for
building structs which asserts it.

Don't try to double free the `_ssl_ssl` and `_ssl_ctx`
provided by `XmlRpcSource`, because this job
is already done by `XmlRpcSource::close()`.
Additionally:
- add a separate non-null check for the _ssl_ctx freeing
- move log lines from `XmlRpcClient::close()` to `XmlRpcSource::close()`
Change-Id: Ifef799fa6a0ffa65b60415f39c51f4b54ff4bb14
Additional logic around these two objects to free it during the
destruction phase.
Also add NULLing for the according pointers in other places
which might also free it before the destructor takes place,
which would lead otherwise to a double free attempt.
Change-Id: I046a660e4b1467a7093dbf2c0c3170a950d5f607
Don't appeal to the XmlRpcSource's members (e.g. `_ssl`)
if this has been freed via `this`.
To check this out see controllable delete behavior
via introduced getter `getsDeletedOnClose()`.
Should fix:
freed_arg: close frees this.

Let STL handle memory management and type safety.
In the future this can be refactored further to eliminate the "Type"
enum and value, as the variant itself keeps this information.
Fix white spacing.

Fix up formatting strings to match the new types and to also fix
incorrect formatting of decimal values.
Remove unused methods.

Directly contain the ValueArray in the variant instead of manually
managing a pointer. Requires updating the return type of some const
functions to also be const, which in turn requires some of their users
to have the type const qualified as well.

When dereferencing it (after creating a new context before)

a connection error, as it might still be NULL and hence
will just seg.fault in this case.

that it may be null, but it has already been dereferenced on all paths leading to the check.

Instead of using the `tmpnam()` which doesn't exclude
race conditions on the system (same filenames created
simultaneously), because it doesn't open/reserve the file,
just use the `mkstemp()` which actually genereates a filename
and creates the file for the process.
Upon creating the file, close the FD, as not needed atm.
This file can be then later opened using `SCPopenAction`
or anything alike.
Current new implementation does not unlink the file from
the filesystem and a user of it has to explicitly do that
later with for example the `sys.unlink()` from this same
library.
Additionally: to be able to have excplicit file path (so dir),
add a second parameter to this function to provide a directory.
Fixes:
warning: the use of `tmpnam' is dangerous, better use `mkstemp'

copying the contained objects ourselves.
