Fix PTHREAD_MUTEX_ADAPTIVE_NP and PTHREAD_MUTEX_ERRORCHECK_NP usage

Browse Source 
The PTHREAD_MUTEX_ADAPTIVE_NP and PTHREAD_MUTEX_ERRORCHECK_NP are
usually not defines, but enum values, so simple preprocessor check
doesn't work.

Check for PTHREAD_MUTEX_ADAPTIVE_NP from the autoconf AS_COMPILE_IFELSE
block and define HAVE_PTHREAD_MUTEX_ADAPTIVE_NP.  This should enable
adaptive mutex on Linux and FreeBSD.

As PTHREAD_MUTEX_ERRORCHECK actually comes from POSIX and Linux glibc
does define it when compatibility macros are being set, we can just use
PTHREAD_MUTEX_ERRORCHECK instead of PTHREAD_MUTEX_ERRORCHECK_NP.
