r/w locks and thread pools. Hide internal structures (using
pthread'ish technics). Place common code in threads.c. Move
no-thread code to thr_stub.c. Move thread pool code to tpool.c.
Removed setconcurrency call from initializer, added 'concurrency'
directive to slapd. Tested code under pthreads, pth, and no-threads.
Move all SunOS routines (ie: _sleep() and its helpers) to thr_lwp.c
so that it's internals can be 'static'. Add 'static' to thr_lwp.c.
Add comment to LWP: NEEDS WORK, may not compile! Need some
SunOS user to sort out the details. Volunteers?
Likely broke things for non-posix threadings....
Update -lldap_r implementation to:
remove attribute support
hide thread detachment
provide concurrency accessors
provide initialization function
fix gethostby{addr,name}_r codes (not coverred by HAVE_REENTRANT_FUNCTIONS)
Update servers/libraries to use ldap_pvt_thread_ calls.
Cleanup server codes (no #ifdef HAVE_PTHREAD_THIS or _THATs)!
Removed -llthread
