5cc22b9326 I was working in the wrong checkout in my last commit... 
revert it, and make the constructor-ness conditional on not being
"standalone".

7d4d667891 Change the constructor attribute to putting this function in the 
.init section.

The constructor is called too late, and clobbers state, leading
to heap corruption later.

1028ce923e Sync with the current sources from onnv-gate. 
The solaris sources use a non-portable create-thread-suspended flag when
spawning the update thread; I've thrown together a pthreads portable
equivalent.  This has not had any real level of testing.

These changes include a lock around the underlying brk() call; the lack of lock
in earlier revisions of this repo may be the reason that
UMEM_OPTIONS=backend=sbrk was flaky.

b9dc821378 move umem_startup constructor to the umem .so itself, rather than 
the malloc replacement.

Rename ec_atomic to umem_atomic.

Add a posix_memalign function.

-ldl isn't universal; make a configure check for it.

49b7cfb4d4 Apparently, the glibc malloc hooks are now deprecated due to thread safety 
issues, so we simply eliminate the glibc specific code from our malloc
preload to resolve this issue.

f82ad44b62 * allow the sbrk backend to be requested via UMEM_OPTIONS=backend=sbrk, but note that this appears to be broken on non-solaris platforms. 
* make a safer/better check for number of cpus on linux
 * use pthread_once to register the forkhandler, as it is possible to call it twice in some scenarios without this protection

41bc866d58 be more libc friendly when replacing malloc(). 
Use our own getenv() on glibc platforms, as the glibc implementation calls
malloc() internally.  This allows the use of env vars to enable debugging modes
in the app.
