Subject: Win32: allow DllMain chaining on the client side (Reworked commits
 e55eb9c, 34a996f from 'mono_libgc' branch)

* configure.ac (enable_win32_dllmain): Recognize new AC "enable"
option.
* configure.ac (GC_INSIDE_DLL): New AC macro (defined only if
enable_win32_dllmain).
* README.macros (GC_INSIDE_DLL): Document.
* include/gc.h (GC_DllMain): Declare as API function (for Win32) if
GC_INSIDE_DLL.
* win32_threads.c (GC_INSIDE_DLL): Recognize (treat the same as
GC_DLL).
* win32_threads.c (DllMain): Rename to GC_DllMain; use GC_API export
declarator if GC_INSIDE_DLL, otherwise define GC_DllMain macro as
a synonym to DllMain.
