The conversions from ssize_t to int need to be typecasted.

If curl_multi_fdset() sets maxfd to -1, the socket detection
loop is skipped and thus !found_new_socket is no cause for alarm.

It makes no difference from curl's point of view but
makes it more convenient to use the tests with a
lws-normalizing proxy between curl and the test server.

They currently only work for 127.0.0.1 which
is hardcoded and can't be easily changed.

.. and add a precheck to skip the test otherwise.

This makes it easier to skip it automatically when
the test suite is used with external proxies.

Trailing spaces were left unmodifed, assuming they were intentional.

Consistently use CRLF instead. The mixed endings weren't
documented so I assume they were unintentional.

This change doesn't matter for curl itself but makes using
the tests with a proxy between curl and the test server
more convenient.

Tests that consistently use no carriage returns were
left unmodified as one can easily work around this.

DNS cache entries populated with CURLOPT_RESOLVE were not properly freed
again when done using the multi interface.

Test case 1502 added to verify.

If we use memory functions (malloc, free, strdup etc) in C sources in
libcurl and we fail to include curl_memory.h or memdebug.h we either
fail to properly support user-provided memory callbacks or the memory
leak system of the test suite fails.

After Ajit's report of a failure in the first category in http_proxy.c,
I spotted a few in the second category as well. These problems are now
tested for by test 1132 which runs a perl program that scans for and
attempts to check that we use the correct include files if a memory
related function is used in the source code.

Fixed checksrc warnings

They broke the NTLM tests from 2023 to 2031.

Re-send ACK for block X in case we receive block X data again while
waiting for block X+1.

Based on an earlier patch by Marcin Adamski.

When nothing is told to configure, we should not enforce switching off
debug options with -g0 (or similar). We instead don't use -g at all in
that situaion and therefore allow the user's CFLAGS settings possibly
dictate what to do.

And fix some newlines to be proper CRLF

Bug: http://curl.haxx.se/bug/view.cgi?id=3586741

It either causes increased memory usage or exposes users
to the "CRIME attack" (CVE-2012-4929)

The {MD5,SHA1,SHA256}_Init functions from OpenSSL are called directly
without any wrappers and they return 1 for success, 0 otherwise.  Hence,
we have to use the same approach in all the wrapper functions that are
used for the other crypto libraries.

This commit fixes a regression introduced in commit dca8ae5f.

Bug: http://curl.haxx.se/bug/view.cgi?id=3586338

When using only 1 second precision, curl doesn't create new cnonce
values quickly enough for all uses.

For example, issuing the following command multiple times to a recent
Tomcat causes authentication failures:

curl --digest -utest:test http://tomcat.test.com:8080/manager/list

This is because curl uses the same cnonce for several seconds, but
doesn't increment the nonce counter.  Tomcat correctly interprets
this as a replay attack and rejects the request.

When microsecond-precision is available, this commit causes curl to
change cnonce values much more frequently.

With microsecond resolution, increasing the nounce length used in the
headers to 32 was made to further reduce the risk of duplication.

Instead of relying on the generic CURLE error for SCP or SFTP send
failures, try passing back a more suitable error if possible.
