3p cmake: Added note about why we need to build all 4 link strats for boost.
3p cmake: Changed order of boost args.
build: Put mswin-specific scripts into mswin subdir.
3p cmake upates.

- Added suffix to unittest++'s debug lib output. It now properly
coexists next to the release lib.
- Removed config-specific dir in 3p installed path.
- Moved config-specific dir in 3p build path to after third_party/builds.
cmake: boost build updates.

- Compiler settings now correctly make it into bjam. We do not specify
any link settings.
- We now use --build-type=complete instead of a subset of link strats.
It's too much work to muck about finding what cmake is going to use and
getting boost to build the right combinations. For now, it just builds
everything and we're done with it. The full build on my laptop took 15 min
for all of 3rd party. This is acceptable, because it won't happen very often.
- For now, boost build uses -j8. If we can get a better number from cmake w/o
per-plat env tests, we'll use that.
3p cmake: Updated notes about cmake/ssl.
3p cmake: Added -dbg suffix to debug zlib builds.
3p build: Changed "third_party" dir to "third-party".
cmake updates.

- meta, test, and meta-test link on linux.
- meta-test runs automatically as part of build. Test succeeds.
