md5: remove use of CommonCrypto-to-OpenSSL macros for the benefit of Leopard

For some reason, OS X 10.5's GCC suddenly stopped working correctly with
macros that change MD5_Init etc. in the code to CC_MD5_Init etc., so I
worked around this by removing use of the macros and inserting static
functions that just call CommonCrypto's implementations of the functions
instead.

md5 & metalink: use better build macros on Apple operating systems

instead of those macros.

build: fix circular header inclusion with other packages

This commit renames lib/setup.h to lib/curl_setup.h and
renames lib/setup_once.h to lib/curl_setup_once.h.

Removes the need and usage of a header inclusion guard foreign
to libcurl. [1]

Removes the need and presence of an alarming notice we carried
in old setup_once.h [2]

----------------------------------------

1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard
up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H,
this single inclusion guard is enough to ensure that inclusion of
lib/setup_once.h done from lib/setup.h is only done once.

Additionally lib/setup.h has always used __SETUP_ONCE_H macro to
protect inclusion of setup_once.h even after commit ec691ca3, this
was to avoid a circular header inclusion triggered when building a
c-ares enabled version with c-ares sources available which also has
a setup_once.h header. Commit ec691ca3 exposes the real nature of
__SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard
foreign to libcurl belonging to c-ares's setup_once.h

The renaming this commit does, fixes the circular header inclusion,
and as such removes the need and usage of a header inclusion guard
foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl.

2 - Due to the circular interdependency of old lib/setup_once.h and the
c-ares setup_once.h header, old file lib/setup_once.h has carried
back from 2006 up to now days an alarming and prominent notice about
the need of keeping libcurl's and c-ares's setup_once.h in sync.

Given that this commit fixes the circular interdependency, the need
and presence of mentioned notice is removed.

All mentioned interdependencies come back from now old days when
the c-ares project lived inside a curl subdirectory. This commit
removes last traces of such fact.

mem-include-scan: verify memory #includes

If we use memory functions (malloc, free, strdup etc) in C sources in
libcurl and we fail to include curl_memory.h or memdebug.h we either
fail to properly support user-provided memory callbacks or the memory
leak system of the test suite fails.

After Ajit's report of a failure in the first category in http_proxy.c,
I spotted a few in the second category as well. These problems are now
tested for by test 1132 which runs a perl program that scans for and
attempts to check that we use the correct include files if a memory
related function is used in the source code.

Previously the Metalink code used Apple's CommonCrypto library only if
curl was built using the --with-darwinssl option. Now we use CommonCrypto
on all Apple operating systems including Tiger or later, or iOS 5 or
later, so you don't need to build --with-darwinssl anymore. Also rolled

Fixed compile error with GNUTLS+NETTLE

In nettle/md5.h, md5_init and md5_update are defined as macros to
nettle_md5_init and nettle_md5_update respectively. This causes
error when using MD5_params.md5_init and md5_update. This patch
renames these members as md5_init_func and md5_update_func to
avoid name conflict. For completeness, MD5_params.md5_final was
also renamed as md5_final_func.

The changes in curl_ntlm_core.c is conversion error and fixed by
casting to proper type.
