Eventually, we may fully break off the extent module; but not for some time. If
it's going to live on in a non-transitory state, it might as well have the nicer
name.
This will eventually completely wrap the eset, and handle concurrency,
allocation, and deallocation. For now, we only pull out the mutex from the
eset.
Refactored core profiling codebase into two logical parts:
(a) `prof_data.c`: core internal data structure managing & dumping;
(b) `prof.c`: mutexes & outward-facing APIs.
Some internal functions had to be exposed out, but there are not
that many of them if the modularization is (hopefully) clean enough.
Prof logging is conceptually seperate from core profiling, so
split it out as a module of its own. There are a few internal
functions that had to be exposed but I think it is a fair trade-off.

`prof.c` is growing too long, so trying to modularize it. There are
a few internal functions that had to be exposed but I think it is a

The file is included in the list of source files in Makefile.in,
but it is missing from the project files. This causes the
build to fail due to unresolved symbols.
The external linkage for spin_adaptive was not used, and the inline
declaration of spin_adaptive that was used caused a probem on FreeBSD
where CPU_SPINWAIT is implemented as a call to a static procedure for
x86 architectures.
Conditionalize use of --whole-archive on the platform plus compiler,
rather than on the ABI. This fixes a regression caused by
7b24c6e557 (Use --whole-archive when
linking integration tests on MinGW.).
