4bcb1430a8 Import jemalloc a8f8d7540d66ddee7337db80c92890916e1063ca (dev branch, 
prior to 3.0.0 release).  This fixes several bugs related to memory
initialization.

Mangle __jemalloc_a0{malloc,calloc,free}() just like all the other
library-internal symbols in jemalloc, and adjust the tls allocation code
in libc to use the mangled names.

a4bd5210d5 Import jemalloc 9ef7f5dc34ff02f50d401e41c8d9a4a928e7c2aa (dev branch, 
prior to 3.0.0 release) as contrib/jemalloc, and integrate it into libc.
The code being imported by this commit diverged from
lib/libc/stdlib/malloc.c in March 2010, which means that a portion of
the jemalloc 1.0.0 ChangeLog entries are relevant, as are the entries
for all subsequent releases.

54da2fb8f2 - Switch ARM and MIPS to TLS Variant I 
- Fix TLS allocation  for Variant I: both rtld and libc allocators
    assume that tls_static_space includes space for TLS structure.
    So increment calculated static size by the size of it.

9436852167 The static TLS size as given by tls_static_space includes TLS_TCB_SIZE 
bytes of TCB in variant I.

dfe2d491c0 o Add MIPS to the list of architectures with defined TLS_TCB_ALIGN 
o Stick with TLS Variant II for MIPS for the moment.

0031cdf4d7 Don't assert() the TLS allocation requested is big enough; just 
fix the argument.

In particular, this is a step towards breaking crt1's dependence on stdio.

3614156c7d Fix the variant I allocation for KSE: Allow a larger TCB and assume 
that the documented TCB is at the tail of the extended TCB. In other
words, the base of the TCB has a negative offset from the TLS.
