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.

by using API instead of accessing an internal structure.
This is required starting OpenSSL 1.1.0-pre3.

Closes #650

Change the example in the docs for CURLOPT_CONNECTTIMEOUT_MS to use
CURLOPT_CONNECTTIMEOUT_MS instead of CURLOPT_CONNECTTIMEOUT.

libssh2_scp_recv2 is introduced in libssh2 1.7.0 - to be released "any

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.

As the winbuild/* stuff uses it!

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.

Closes #626

Since we didn't keep the input argument around after having called
mbedtls, it could end up accessing the wrong memory when figuring out
the ALPN protocols.

Closes #642

For example something like --output \\?\C:\foo

As of https://boringssl-review.googlesource.com/#/c/6980/, almost all of
BoringSSL #ifdefs in cURL should be unnecessary:

- BoringSSL provides no-op stubs for compatibility which replaces most
  #ifdefs.

- DES_set_odd_parity has been in BoringSSL for nearly a year now. Remove
  the compatibility codepath.

- With a small tweak to an extend_key_56_to_64 call, the NTLM code
  builds fine.

- Switch OCSP-related #ifdefs to the more generally useful
  OPENSSL_NO_OCSP.

The only #ifdefs which remain are Curl_ossl_version and the #undefs to
work around OpenSSL and wincrypt.h name conflicts. (BoringSSL leaves
that to the consumer. The in-header workaround makes things sensitive to
include order.)

This change errs on the side of removing conditionals despite many of
the restored codepaths being no-ops. (BoringSSL generally adds no-op
compatibility stubs when possible. OPENSSL_VERSION_NUMBER #ifdefs are
bad enough!)

Closes #640

Allow --output to reserved dos device names without the device prefix
for backwards compatibility.

Example: --output NUL can be used instead of --output \\.\NUL

It turns out Firefox and Chrome both allow spaces in cookie names and
there are sites out there using that.

Turned out the code meant to strip off trailing space from cookie names
didn't work. Fixed now.

Test case 8 modified to verify both these changes.

Closes #639

When trying to verify a peer without having any root CA certificates
set, this makes libcurl use the TLS library's built in default as
fallback.

RFC 7230 says we should stop. Firefox already stopped.
