tvg file stores the version info of thorvg when it's generated,
in order to compare it with the runtime thorvg version when it's loaded.
For this, thorvg builds up the current version of symbol on the initilaization step,
that can be referred by the tvg loader.
When memory is not allocated successully, it must return the FailedAllocation as the return value.
Previous initializer wrongly returns the value that case, this corrects it.
Introduced the reference counting for the backend engines so that
tvg prevents unpaired engine initialization/termination calls by user mistake.
@Issues: 296
we introduced shared memory pool for avoiding reallocate memory
while it process the stroke outlines, It experimentally increase
the outline data if we use the allocated memory for multiples shape strokes,
we don't need to alloc/free memory during the process.
This shared outline memory is allocated for threads count
so that we don't interrupt memory access during the tasks.
@Issues: 75
we should avoid code insertion during file dependencies,
such as #include "xxx.h" which has implementations.
This could increase binary size, we can avoid it as possible.
Current patch improves binary size like this:
From: file(2059008) = text(120360) data(8096) bss(80) dec(128536)
To : file(1921832) = text(118429) data(7872) bss(56) dec(126357)
More additional patches will come in to optmize binary size.
initialization interfaces has been changed for threads count.
if you want to set concrete threads count by system, please specify thread count with it.
std threads:
tvg::Initializer::init(tvg::CanvasEngine::Sw, std:🧵:hardware_concurrency());
if your system provides designed threads info, you can use it.
efl:
tvg_engine_init(TVG_ENGINE_SW, eina_cpu_count());
I recommend to avoid max threads usage for better performance.

remove unnecessary condition.
implementation won't be included multiple times not like headers.
Thus this condition is unnecessary.
