Update comment, fix spacing. MFC r190885: Change the way the mapping of the ELF objects is constructed, by first mapping PROT_NONE anonymous memory over the whole range, and then mapping the segments of the object over it. MFC r195743: Only perform .bss mapping and cleaning operations when segment file size is not equal to its memory size. Tested by: Mykola Dzham

FreeBSD returns main object handle from dlopen(NULL, ...) calls. dlsym seaches using this handle are expected to look for symbol definitions in all objects loaded at the program start time along with all objects currently in RTLD_GLOBAL scope.

MFC r190324:

2009-05-12T02:17:25Z
Support for a new environment variable, LD_ELF_HINTS_PATH for overriding the rtld hints file. This environment variable would be unset if the process is considered as tainted with setuid/setgid. This feature gives a convenient way of using a custom set of shared library that is not located in the default location and switch back. Feature requested by: iXsystems Original patch by: John Hixson MFC after: 2 weeks

Mostly synchronize lib/libthr and sys/kern/kern_umtx.c with the code

2009-03-24T20:57:10Z
from HEAD. Since libkse is still built on RELENG_7, pthread_cleanup_push/pop are left as the functions, but the support code in libthr is present for the macro versions. Malloc in RELENG_7 does not require thread exit hook, but I decided to add empty handler for it, instead of removing callback from thr_exit(). No mergeinfo since this change is prepared by patching libthr and then bringing in required missed bits.
