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.

- 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.

...
o Stick with TLS Variant II for MIPS for the moment.

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

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.
