Some TFTP server implementations ignore the "TFTP Option extension"
(RFC 1782-1784, 2347-2349), or implement it in a flawed way, causing
problems with libcurl. Another switch for curl_easy_setopt
"CURLOPT_TFTP_NO_OPTIONS" is introduced which prevents libcurl from
sending TFTP option requests to a server, avoiding many problems caused
by faulty implementations.

If any parameter in a HTTP DIGEST challenge message is present multiple
times, memory allocated for all but the last entry should be freed.

First version, try this out!

To hide github specific files somewhat from the rest.

At one point during the development of HTTP/2, the commit 133cdd29
introduced automatic decompression of Content-Encoding as that was what
the spec said then. Now however, HTTP/2 should work the same way as
HTTP/1 in this regard.

nghttp2 callback deals with TLS layer and therefore the header does not
need to be broken into chunks.

This is required starting OpenSSL 1.1.0-pre3.

Bug: https://github.com/curl/curl/pull/651

Remove NOTES section, it's no longer needed since we aren't setting the
errorlevel and more importantly the recently updated URL in the comments
is causing some unusual behavior that breaks the script.

Closes https://github.com/curl/curl/issues/649

The behavior has been clarified in CURLOPT_FTP_USE_{EPRT,EPSV}.3 man
pages since curl-7_12_3~131.  This patch makes it clear in the curl.1
man page, too.

On 32bit systems, make sure we don't overflow and return funky values
for very large time differences.

Closes #646

All plain C examples now (mostly) adhere to the curl code style. While
they are only examples, they had diverted so much and contained all
sorts of different mixed code styles by now. Having them use a unified
style helps users and readability. Also, as they get copy-and-pasted
widely by users, making sure they're clean and nice is a good idea.

573 checksrc warnings were addressed.

cleaning up handles is a good idea as we leak memory otherwise

Also, line wrapped before 80 columns.

It is wasteful to search it backwards if we look for _any_ slash.

We only care if at least one cipher-suite is enabled, so it does
not make any sense to iterate till the end and count all enabled
cipher-suites.
