Reverting tasks to bring qTox in Windows XP

[JeanPaulLucien]

OS: Windows XP Service Pack 3, 32-bit

Installer works well, but qTox was not started. Windows reported about CancelIoEx. I've discovered more:
JeanPaulLucien/Windows-XP-Afterlife#4

Common problem... bcrypt.dll

BCryptCloseAlgorithmProvider
BCryptGenRandom
BCryptOpenAlgorithmProvider

There is good alternatives instead.

swscale-6.dll asks:

InitOnceBeginInitialize
InitOnceComplete

Seems it's about codec. I suggest disable this features for Windows XP, stay "Download audio/video". Because I'm sure there are alternatives.

avutil-57.dll asks:

bcrypt.dll
AcquireSRWLockExclusive
InitOnceBeginInitialize
InitOnceComplete
InitializeConditionVariable
InitializeSRWLock
ReleaseSRWLockExclusive
SleepConditionVariableSRW
WakeAllConditionVariable
WakeConditionVariable

Another one codec.

Seriously. I'm sure I have all codecs are installed.

AVFORMAT-59.DLL:

AcquireSRWLockExclusive
ReleaseSRWLockExclusive

AVCODEC-59.DLL:

AcquireSRWLockExclusive
InitOnceBeginInitialize
InitOnceComplete
InitializeConditionVariable
InitializeSRWLock
ReleaseSRWLockExclusive
SleepConditionVariableSRW
WakeAllConditionVariable
WakeConditionVariable

@JeanPaulLucien
it's unclear where the future of qTox will be.
for now you can try: https://github.com/Zoxcore/trifa_material
it's still in beta. would be interesting to know if it actually works on windows XP

I suppose in this case QtCore library with Windows XP compatibility is needed.
