test557: set a known good numeric locale

Windows does not allow setting the locale with environment variables (as
the test attempted to do), so the test failed when run with a user
locale that has a comma as radixchar. Changed the test to call
setlocale() explicitly to ensure that a known working locale is set even
on Windows.

mprintf: Replaced internal usage of FORMAT_OFF_T and FORMAT_OFF_TU

Following commit 0aafd77fa4c6f2, replaced the internal usage of
FORMAT_OFF_T and FORMAT_OFF_TU with the external versions that we
expect API programmers to use.

This negates the need for separate definitions which were subtly
different under different platforms/compilers.

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.

All C and H files now (should) feature the proper project curl source
code header, which includes basic info, a copyright statement and some
basic disc

remove the CVSish $Id$ lines

Fix variable initialization

Modified test case 557 to additionally verify libcurl's internal curl_m*printf()
functions formatting functionality when handling signed and unsigned shorts.

fix compiler warning: external declaration in primary source file

include "memdebug.h"

Fix wrong signed int formatting string directive in test case #557.

This error did not cause test failures on systems where sizeof(int) == sizeof(long).

Test case 557 now also verifies signed and unsigned int formatting.

Simplify condition check

Update test case 557

Added test case 557 to verify libcurl's internal curl_m*printf() functions
formatting functionality when handling signed and unsigned longs, as well as
our curl_off_t data type.
