build: make use of 76 lib/*.h renamed files

76 private header files renamed to use our standard naming scheme.

This change affects 322 files in libcurl's source tree.

setup_once.h: refactor inclusion of <unistd.h> and <sys/socket.h>

Inclusion of top two most included header files now done in setup_once.h

fix a bunch of MSVC compiler warnings

MemoryTracking: adjust initialization calling

Calling of curl_memdebug() was still done with a pending free()

MemoryTracking: adjust curl_domalloc() and curl_dofree() memory filling

Until 2011-08-17 libcurl's Memory Tracking feature also performed
automatic malloc and free filling operations usi

MemoryTracking: adjust curl_domalloc() and curl_dofree() memory filling

Until 2011-08-17 libcurl's Memory Tracking feature also performed
automatic malloc and free filling operations using 0xA5 and 0x13
values. Our own preinitialization of dynamically allocated memory
might be useful when not using third party memory debuggers, but
on the other hand this would fool memory debuggers into thinking
that all dynamically allocated memory is properly initialized.

As a default setting, libcurl's Memory Tracking feature no longer
performs preinitialization of dynamically allocated memory on its
own. If you know what you are doing, and really want to retain old
behavior, you can achieve this compiling with preprocessor symbols
CURL_MT_MALLOC_FILL and CURL_MT_FREE_FILL defined with appropriate
values.

MemoryTracking: make curl_docalloc() call calloc() avoiding our zero fill

socketpair() usage tracking to allow fd leak detection

stdio.h, stdlib.h, string.h, stdarg.h and ctype.h inclusion done in setup_once.h

remove the CVSish $Id$ lines

fix socket data type and logging format in debug tracking socket functions

fix compiler warning

fix compiler warning

Constantine Sapuntzakis enhancements to make memory tracking log file writing
of messages atomic, on systems where an fwrite of a memory buffer is atomic.

Fix compiler warning: ISO C90 forbids mixed declarations and code

Make memory tracking system intolerant with zero sized malloc(),
calloc() and realloc() function calls.

Fix compiler warning: control reaches end of non-void function

Since the NSS lib closes the socket the memory tracking system wrongly gets a
false positive on a leaked socket, so this introduces a way to tell the system
that the socket is indeed closed w

Since the NSS lib closes the socket the memory tracking system wrongly gets a
false positive on a leaked socket, so this introduces a way to tell the system
that the socket is indeed closed without explicitly closing it!

Use build-time configured curl_socklen_t instead of socklen_t

libcurl's memory.h renamed to curl_memory.h

remove unnecessary typecast

Really old gcc doesn't like parenthesis around the names of functions that
don't have prototypes. They didn't serve any useful purpose here, anyway.

Disable tracking of fdopen() calls in the low-level memory leak tracking
code when fdopen() is not available, to avoid compiler error.

remove dead code portion inoperative long time ago

fix print formatting string directives
