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.

As long as the `TypeInt` is actually a long primitive,
and we tend to switch using the long type everywhere
within xml implementation, then
there is no need to support both `int` and `long`
types, just force users to be on `long` always.
Refactor the user code accordingly.

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()`

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.

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.
CID 542402: (#1 of 1): Read from pointer after free (USE_AFTER_FREE)
use_after_free: Using freed pointer 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.

Store integers as long to reduce likelihood of overflows. Retain
overloaded accessors for compatibility.
Use time_t and suseconds_t for timestamps.
Fix up formatting strings to match the new types and to also fix
incorrect formatting of decimal values.
Remove unused methods.

Add missing initialisers and fix order.
In some cases the member was actually unused and could just be removed.

Give an exact size of the buf to the `snprintf()` and also treat the
returned value from it to eliminate this warning:

We should provide a proper formation of the timestamp
in the `timeToXml()`. Just unify that in the manner
it's done in the rest of places.
It will fix then this:
