Previously, we made the user deal with this themselves, but that's not good
enough; if hooks may allocate, we should test the allocation pathways down
hooks. If we're doing that, we might as well actually implement the protection
for the user.
The hook module allows a low-reader-overhead way of finding hooks to invoke and
calling them.
For now, none of the allocation pathways are tied into the hooks; this will come
later.
"Hooks" is really the best name for the module that will contain the publicly
exposed hooks. So lets rename the current "hooks" module (that hook external
dependencies, for reentrancy testing) to "test_hooks".
We're about to need an atomic uint8_t for state operations.
Unfortunately, we're at the point where things won't get inlined into the key
methods unless they're force-inlined. This is embarassing and we should do
something about it, but in the meantime we'll force-inline a little more when we
need to.
When configured with --with-lg-page, it's possible for the configured page size
to be greater than the system page size, in which case the page address may only
be aligned with the system page size.
When configuring out-of-tree (source directory is not build directory),
the generated include files from the build directory should have higher
priority than those in the source dir.
This is especially helpful when cross-compiling.

This patch allows to override the lg-vaddr values, which
are defined by the build machine's CPUID information (x86_64)
or default values (other architectures like aarch64).

Instead of setting a fix value of 48 allowed VA bits,
we distiguish between LP64 and ILP32.
Testsuite result with LP64:
Test suite summary: pass: 13/13, skip: 0/13, fail: 0/13
Testsuit result with ILP32:
Test suite summary: pass: 13/13, skip: 0/13, fail: 0/13

Previously, we would leak the extent and memory associated with a salvageable
portion of an extent that we were trying to split in three, in the case where
the first split attempt succeeded and the second failed.
Right now we always make our TLS use the initial-exec model if the compiler
supports it. This change allows configure-time disabling of this setting, which
can be helpful when dynamically loading jemalloc is the only option.
