Document Curl_gmtime() and define away the old functions so that they
won't be used internally again by mistake.

Instead of polluting many places with #ifdefs, we create a single place
for this function, and also check return code properly so that a NULL
pointer returned won't cause problems.

The official Mozilla page at http://www.mozilla.org/projects/security/certs/
points out a new place as the "proper" place to get Mozilla's CA certs from
so this script is now updated to use that instead.

"SSL: couldn't create a context" really isn't that helpful, now it'll
also extract an explanation from OpenSSL and append to the right.

The code in the toofast state needs to first recalculate the values
before it uses them again since it may have been a while since it last
did it when it reaches this point.

This will be used by file_do() and Curl_readwrite() as a unified method
of checking to see if a remote document meets the supplied
CURLOPT_TIMEVAL and CURLOPT_TIMECONDITION.

The double name resolve trick used with c-ares could leave allocated
memory in 'temp_ai' if the operation was aborted in the middle.

When this callback is called due to the destruction of the ares handle,
the connection pointer passed in as an argument may no longer pointing
to valid data and this function doesn't need to do anything with it
anyway so we make sure it doesn't.

Bug: https://bugzilla.redhat.com/670802

The HTTP parser allocated memory on each received Location: header
without properly freeing old data. Starting now, the code only considers
the first Location: header and will blissfully ignore subsequent ones.

... and update the curl.1 and curl_easy_setopt.3 man pages such that
they do not suggest to use an OpenSSL utility if curl is not built
against OpenSSL.

Get rid of stdout redirection to NUL and move stderr redirection
into RM and RMDIR macros.

Check for BCCDIR environment var done now as other checks.

Borland's $(MAKEDIR) expands to the path where make.exe is located,
use this feature to define BCCDIR when user has not defined BCCDIR.

The idea that the protocol and socktype is part of name resolving in the
libc functions is nuts. We keep the name resolver functions assume
TCP/STREAM and we make sure that when we want to connect to a UDP
service we use the correct UDP/DGRAM set instead. This bug was because
the ->protocol field was not always set correctly.

This bug was only affecting ipv6-disabled non-cares non-threaded builds.

The just added speedcheck must not ruin the error code if already set
due to a problem.

Check for speedcheck limits during the state machine traversals

As the function doesn't really use the connectdata struct but only the
SessionHanadle struct I modified what argument it wants.

512 bytes turned out too short for some data, so now we allocate a
larger buffer instead

When configure --enable-debug has been used, all files in lib/ are now
built twice and a separate static library crafted for unit-testing will
be linked. The unit tests in the tests/unit subdir will use that
library.

We cannot assume that PATH_MAX will be enough for the remote path name
so allocating room for it is the only sensible approach.
