Update inflateBack() comments, since inflate() can be faster.
Use underscored I/O function names for WINAPI_FAMILY.

Suggested by E. Timothy Uy.
Add _tr_flush_bits to the external symbols prefixed by --zprefix.
Add contrib/vstudio/vc10 pre-build step for static only.

Also correct typo for 64-bit debug build.
Quote --version-script argument in CMakeLists.txt.

Previously, spaces in ${CMAKE_CURRENT_SOURCE_PATH} would expand into
multiple linker arguments.
Don't specify --version-script on Apple platforms in CMakeLists.txt.

Mac OS X's linker (derived from LLVM, not GNU binutils) does not support
--version-script. Don't specify it on this platform.
Fix casting error in contrib/testzlib/testzlib.c.
Fix types in contrib/minizip to match result of get_crc_table().
Simplify contrib/vstudio/vc10 with 'd' suffix.
Add TOP support to win32/Makefile.msc.

Facilitate multi-platform compilation, e.g.:
nmake -f pathto\zlib\win32\Makefile.msc TOP=pathto\zlib
Suport i686 and amd64 assembler builds in CMakeLists.txt.

 * Use -DASM686=1 to build with i686 asm.
 * Use -DAMD64=1 to build with amd64 asm.
Fix typos in the use of _LARGEFILE64_SOURCE in zconf.h.
