curl/mprintf.h: remove support for _MPRINTF_REPLACE

Browse source 
The define is not in our name space and is therefore not protected by
our API promises.

It was only really used by libcurl internals but was mostly erased from
there already in 8aabbf5 (March 2015). This is supposedly the final
death blow to that define from everywhere.

As a side-effect, making sure _MPRINTF_REPLACE is gone and not used, I
made the lib tests in tests/libtest/ use curl_printf.h for its redefine
magic and then subsequently the use of sprintf() got banned in the tests
as well (as it is in libcurl internals) and I then replaced them all
with snprintf().

In the unlikely event that any users is actually using this define and
gets sad by this change, it is very easily copied to the user's own
code.

Like curl_maprintf() but takes a va_list pointer argument instead of a
variable amount of arguments.
.RE
To easily use all these cloned functions instead of the normal ones, #define
_MPRINTF_REPLACE before you include the <curl/mprintf.h> file. Then all the
normal names like printf, fprintf, sprintf etc will use the curl-functions
instead.
.SH AVAILABILITY
These function will be removed from the public libcurl API in a near
future. They will instead be made "available" by source code access only, and
then as curlx_-prefixed functions. See lib/README.curlx for further details.
These functions will be removed from the public libcurl API in the future. Do
not use them in any new programs or projects.
.SH RETURN VALUE
The \fBcurl_maprintf\fP and \fBcurl_mvaprintf\fP functions return a pointer to
a newly allocated string, or NULL if it failed.
