A regression introduced in 7f3b87d8 (present in the 7.21.4 release)
broke the total parser. Now skip the whitespace and the digits.

Verify the change brought in commit 8e11731653061. It makes sure that
returning a failure from the progress callback even very early results
in the correct return code.

When the progress callback returned 1 at a very early state, the code
would not make CURLE_ABORTED_BY_CALLBACK get returned but the process
would still be interrupted. In the HTTP case, this would then cause a
CURLE_GOT_NOTHING to erroneously get returned instead.

memdebug.h already contains all required definitions and including
curl_memory.h causes errors like the following:

tests/unit/unit1394.c:119: undefined reference to `Curl_cfree'
tests/unit/unit1394.c:120: undefined reference to `Curl_cfree'

This is a debug function only and serves no purpose in production code,
it only slows things down. I left the code #ifdef'ed for possible future
pipeline debugging.

Also, this was a global function without proper namespace usage.

If OpenSSL is built to support SSLv2 this brings back the ability to
explicitly select that as a protocol level.

This fixes two markup typos I noticed in curl_easy_setopt.3.  (The use
of bold vs. italics seems a bit inconsistent in that page, but it should
at least be valid man syntax.)

Some feedback provided by byte_bucket on IRC pointed out that commit
db11750c wasn’t really correct because it allows for “upgrading” to a
newer protocol when it should be only allowing for SSLv3.

This change fixes that.

When SSLv3 connection is forced, don't allow SSL negotiations for newer
versions.  Feedback provided by byte_bucket in #curl.  This behavior is
also consistent with the other force flags like --tlsv1.1 which doesn't
allow for TLSv1.2 negotiation, etc

Updated the contents of the email and payload callback as per the IMAP
and other SMTP examples.

Since ad34a2d5 (present in 7.34.0 release) forcing
SSLv3 will always return the error "curl: (35) Unsupported SSL protocol
version" Can be replicated with `curl -I -3 https://www.google.com/`.
This fix simply allows for v3 to be forced.

...and made some minor coding style changes to better match the curl
coding standards as well as the other email related examples.

Following commit 0aafd77f, 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.

Added support to the built-in printf() replacement functions, for these
non-ANSI extensions when compiling under Visual Studio, Borland, Watcom
and MinGW.

This fixes problems when generating libcurl source code that contains
curl_off_t variables.

Although added to CURLOPT_INFILESIZE in commit ee3d3adc it was
never added to CURLOPT_INFILESIZE_LARGE.
