* Makefile.in (VPATH): Add regex directory.

(NM): new variable.
(OBSOLETE_FUNCTIONS): Ditto.
(NEW_FUNCTIONS): Ditto.
(install-headers): Install regex.h.
(install-man): New target.
(install): Use new target.
(DLL_OFILES): Add v8_reg* stuff.
(new-cygwin1.dll): Eliminate stamp-cygwin-lib creation.
(libcygwin.a): Remove obsolete functions from import lib.  Add new functions.
* configure.in: Detect 'nm' tool.
* configure: Regenerate.
* cygwin.din: Export posix_reg* functions.  Eliminate export of v8 reg*
functions.  This is now handled in object files themselves.
* regex/*: New files.
* regexp/v8_*.c: New files, renamed from non v8_ equivalents.
