Build: Remove cargo-cult macro definitions - _REENTRANT and _THREAD_SAFE were taken from the VLC build system and have since been removed there, so it seems safe to remove those here as well. - _POSIX_PTHREAD_SEMANTICS is required for POSIX thread flavor of threading functions but instead we can define _POSIX_C_SOURCE to a value higher than 199506L, when including <pthread.h>, see https://docs.oracle.com/cd/E19455-01/806-5257/compile-3/index.html - __EXTENSIONS__ is used to enable Solaris extensions, as far as I know we are not using any. - _FILE_OFFSET_BITS is already defined to 64 by meson. - _ISOC99_SOURCE should not be required as we do not support compiling with -std c89. - _ISOC11_SOURCE should not be required as we set -std c11, so we do not need any C11 extensions to C99 as we already use C11. - _POSIX_SOURCE is not required as we already set _POSIX_C_SOURCE to a positive integer. * _XOPEN_SOURCE should not be needed as we already have _POSIX_C_SOURCE. * _XOPEN_SOURCE_EXTENDED should not be required as we do not need any X/Open Unix extensions to my knowledge. * _BSD_SOURCE should not be required as we already set _POSIX_C_SOURCE. * _SVID_SOURCE should not be required as we already set _POSIX_C_SOURCE.
