This file wasn't included in commit 4af40b36 which updated all
haxx.se http urls to https. The file was committed prior to that update,
but may have been merged after it and hence didn't get updated.

... instead of previous separate struct fields, to make it easier to
extend and change individual backends without having to modify them all.

closes #2547

Curl_setup_transfer() can be called to setup a new individual transfer
over a multiplexed connection so it shouldn't unset writesockfd.

Closes #2549

They are removed from the compiler flags.

This ensures that make dependency tracking will force a rebuild whenever
configure --enable-debug or --enable-curldebug changes.

Closes #2548

It triggers an assert.

When only building with SSL backends that don't use the CA bundle file
(by default), skip the check.

ssh-libssh.c:2429:21: warning: result of '1 << 31' requires 33 bits to
represent, but 'int' only has 32 bits [-Wshift-overflow=]

'len' will never be that big anyway so I converted the run-time check to
a regular assert.

Commit 3c630f9b partially reverted the
changes from commit dd7521bc because of
the problem that strcpy_url() was modified unilaterally without also
modifying strlen_url(). As a consequence strcpy_url() was again
depending on ASCII encoding.

This change fixes strlen_url() and strcpy_url() in parallel to use a
common host-encoding independent criterion for deciding whether an URL
character must be %-escaped.

This reverts commit d5d683a9.

--disable-pthreads can be used to disable pthreads and get the threaded
resolver to use the windows threading when building with mingw.

Fixes #2533
Closes #2540

Commit 2bc230de made the macro MAX_COOKIE_LINE_TXT become unused,
so remove as it's not part of the published API.

Closes https://github.com/curl/curl/pull/2537

This extends the INDENTATION case to also handle 'else' statements
and require proper indentation on the following line. Also fixes the
offending cases found in the codebase.

Closes #2532

This function can get called on a connection that isn't setup enough to
have the 'recv_underlying' function pointer initialized so it would try
to call the NULL pointer.

Closes #2536

Follow-up to 1514c446: replace another strstr() call done on a
buffer that might not be zero terminated - with a memchr() call, even if
we know the substring will be found.

Closes #2534

WolfSSL doesn't enable it by default anymore

All occurrences of assignment within conditional expression in
os400sys.c rewritten into two steps: first assignment and then the check
on the success of the assignment. Also adjust related incorrect brace
positions to match project indentation style.

This was spurred by seeing "if((inp = input_token))", but while in there
all warnings were fixed.

There should be no functional change from these changes.

Closes #2525

The jar should be written iff there are cookies, so ensure that we still
have cookies after expiration to avoid creating an empty file.
