Having recently added support for building git-imap-send on
Windows, we now link against OpenSSL libraries, and the linker
issues the following warning:
warning LNK4044: unrecognized option '/lssl'; ignored
In order to suppress the warning, we change the msvc linker
script to translate an '-lssl' parameter to the ssleay32.lib
library.
Note that the linker script was already including ssleay32.lib
(along with libeay32.lib) as part of the translation of the
'-lcrypto' library parameter. However, libeay32.dll does not
depend on ssleay32.dll and can be used stand-alone, so we remove
ssleay32.lib from the '-lcrypto' translation.
The dependence of ssleay32.dll on libeay32.dll is represented in
the Makefile by the NEEDS_CRYPTO_WITH_SSL build variable.
Also, add the corresponding change to the buildsystem generator.

* ef/msys-imap:
Windows: use BLK_SHA1 again
MSVC: Enable OpenSSL, and translate -lcrypto
mingw: enable OpenSSL
mingw: wrap SSL_set_(w|r)fd to call _get_osfhandle
imap-send: build imap-send on Windows
imap-send: fix compilation-error on Windows
imap-send: use run-command API for tunneling
imap-send: use separate read and write fds
imap-send: remove useless uid code
We don't use crypto, but rather require libeay32 and
ssleay32. handle it in both the Makefile msvc linker
script, and the buildsystem generator.

During an MSVC build on cygwin, the make program did not notice
when the compiler or linker exited with an error. This was caused
by the scripts exiting with the value returned by system() directly.
On POSIX-like systems, such as cygwin, the return value of system()
has the exit code of the executed command encoded in the first byte
(ie the value is shifted up by 8 bits). This allows the bottom
7 bits to contain the signal number of a terminated process, while
the eighth bit indicates whether a core-dump was produced. (A value
of -1 indicates that the command failed to execute.)
The make program, however, expects the exit code to be encoded in the
bottom byte. Futhermore, it apparently masks off and ignores anything
in the upper bytes.
However, these scripts are (naturally) intended to be used on the
windows platform, where we can not assume POSIX-like semantics from
a perl implementation (eg ActiveState). So, in general, we can not
assume that shifting the return value right by eight will get us
the exit code.
In order to improve portability, we assume that a zero return from
system() indicates success, whereas anything else indicates failure.
Since we don't need to know the exact exit code from the compiler
or linker, we simply exit with 0 (success) or 1 (failure).

Enable MSVC builds with GNU Make by simply calling
make MSVC=1
(Debug build possible by adding DEBUG=1 as well)
Two scripts, clink.pl and lib.pl, are used to convert certain GCC
specific command line options into something MSVC understands.
By building for MSVC with GNU Make, we can ensure that the MSVC
port always follows the latest code, and does not lag behind due
to unmaintained NMake Makefile or IDE projects.
