Bugzilla bug #17223: added the PR_MSG_PEEK (with same value as MSG_PEEK)
for PR_Recv(). Define _PR_EMULATE_MSG_PEEK on platforms that don't natively support MSG_PEEK. Implemented PR_MSG_PEEK for pthreads. Added the peek.c test case. Modified files: prio.h, _macos.h, _winnt.h, primpl.h, ptio.c, pr/tests/Makefile, pr/tests/Makefile.in Added file: pr/tests/peek.c
