MFC: Merge malloc(3) improvements and fixes. The highlights are:2008-03-07T22:39:39ZJason Evansjasone@FreeBSD.org2008-03-07T22:39:39Zurn:sha1:d25eaea3901102b810ad0b75e3f464935b2b95ca
* Avoid re-zeroing memory in calloc() when possible.
* Use pthread mutexes where possible instead of libc "spinlocks", and
actually spin some during contention before blocking.
* Implement dynamic load balancing of thread-->arena mapping.
* Avoid floating point math in order to avoid increased context switch
overhead for applications that otherwise would not use floating point
math.
* Restructure how sbrk() and mmap() are used to acquire memory mappings.
This provides a way to force malloc to only use sbrk(), which can be
useful in the context of resource limits.
* Reduce the number of mmap() calls typically necessary when allocating
a chunk.
* Track dirty unused pages so that they can be purged if they exceed a
threshold.
* Try to realloc() large objects in place.
* Manage page runs with trees instead of chunk maps, which allows
logarithmic-time run allocation.
MFC changes from 1.14 for sys/lock.c and 1.127+1.128 for thread/thr_kern.c2008-02-04T19:59:40ZJulian Elischerjulian@FreeBSD.org2008-02-04T19:59:40Zurn:sha1:0f4ea69cd7571934707105457f0793e04fc57abf
this copes with the fact that during a fork the child may get
really screwy state in the threading system due to the
sudden vaporisation of it's sibling threads.

Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it.2007-05-13T14:12:40ZDaniel Eischendeischen@FreeBSD.org2007-05-13T14:12:40Zurn:sha1:00fb440c1a145b56b6c75fd405d80071aef2aab1
Warning, after symbol versioning is enabled, going back is not easy
(use WITHOUT_SYMVER at your own risk).
Change the default thread library to libthr.
There most likely still needs to be a version bump for at least the
thread libraries. If necessary, this will happen later.
Catch up with the renaming of the private version namespace.2007-04-29T15:27:23ZDaniel Eischendeischen@FreeBSD.org2007-04-29T15:27:23Zurn:sha1:23daef56b332c87464267d68013fe6e8d7580d47
