Convert all msvcrt locks over to use _lock and _unlock.
Explicitly make msvcrt compile with multithreaded option.
Fix flag handling in _sopen. Add W->A call for new _swopen.

- Implement ordinals 155, 350, 351, 352, 418, 436.
- Fake implementation of SHGetInverseCMAP.
- Stub ordinal 209.
- Fix definition of ordinal 7.
- Implement SHGetThreadRef and SHSetThreadRef.

old-style config.cache.

Added make rules for building and running C unit tests.

- made changes to the precompiler directives to check for specific
  features instead of checking for the environment version.

- Fix brainfade in previous delta
- Move ellipsification results to static memory; they are going to
  have to be referenced inside NextLineW and the arg list is too big
  already.
- Add the missing ellipsification result (len_under) to simplify coding.
- Slight correction to prefix tracking for when there are several
  underlined characters on a single line (DT_EXPANDTABS only).
- Allocate and free the temporary copy required for DT_MODIFYSTRING
  rather than using a fixed size stack array.
- Introduce lastline into the main loop; it simplifies the code and we
  are going to need it.

support multiline ellipsification etc.  Rather than measuring the text
each time we add a character and breaking once it is too long and
WORDBREAK is enabled, we copy a whole text segment and then measure
it; GetTextExtentPointEx is designed to tell us how much fitted.  This
may result in a little rescanning if wordbreak is enabled but will be
well worth while when multiline path ellipsification is brought down
into the NextLine function.  Note also that the wordbreak calculation
is a little more complete (e.g.  including break-within-word for
DT_EDITCONTROL).

freeing the memory (fixes copy/paste in mail body in Forte Agent).

wordbreaking on singleline text.

destination is to be treated as a directory and handle those cases.

Changed a few things to better follow the autoconf guidelines.
