connect: treat an interface bindlocal() problem as a non-fatal error
I am using curl_easy_setopt(CURLOPT_INTERFACE, "if!something") to force
transfers to use a particular interface but the transfer fails with
CURLE_INTERFACE_FAILED, "Failed binding local connection end" if the
interface I specify has no IPv6 address. The cause is as follows:
The remote hostname resolves successfully and has an IPv6 address and an
IPv4 address.
cURL attempts to connect to the IPv6 address first.
bindlocal (in lib/connect.c) fails because Curl_if2ip cannot find an
IPv6 address on the interface.
This is a fatal error in singleipconnect()
This change will make cURL try the next IP address in the list.
Also included are two changes related to IPv6 address scope:
- Filter the choice of address in Curl_if2ip to only consider addresses
with the same scope ID as the connection address (mismatched scope for
local and remote address does not result in a working connection).
- bindlocal was ignoring the scope ID of addresses returned by
Curl_if2ip . Now it uses them.

util.c: Made write_pidfile write the correct PID on MinGW/Msys
This workaround fixes an issue on MinGW/Msys regarding the Perl
testsuite scripts not being able to signal or control the server
processes. The MinGW Perl runtime only sees the Msys processes and
their corresponding PIDs, but sockfilt (and other servers) wrote the
Windows PID into their PID-files. Since this PID is useless to the
testsuite, the write_pidfile function was changed to search for the
Msys PID and write that into the PID-file.

SO_SNDBUF: don't set SNDBUF for win32 versions vista or later
The Microsoft knowledge-base article
http://support.microsoft.com/kb/823764 describes how to use SNDBUF to
overcome a performance shortcoming in winsock, but it doesn't apply to
Windows Vista and later versions. If the described SNDBUF magic is
applied when running on those more recent Windows versions, it seems to
instead have the reversed effect in many cases and thus make libcurl
perform less good on those systems.
This fix thus adds a run-time version-check that does the SNDBUF magic
conditionally depending if it is deemed necessary or not.

ftp_sendquote: use PPSENDF, not FTPSENDF
The last remaining code piece that still used FTPSENDF now uses PPSENDF.
In the problematic case, a PREQUOTE series was done on a re-used

pointers. The init call is done properly from Curl_pp_sendf() so this
change fixes this particular crash.

Modified sws to support and use custom CONNECT responses instead of the

extract test case number from the host name in a CONNECT request by
finding the number after the last dot. It makes 'machine.moo.123' use
test case 123.

WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage
As of 25-mar-2013 wcsdup() _wcsdup() and _tcsdup() are only used in
WIN32 specific code, so tracking of these has not been extended for
other build targets. Without this fix, memory tracking system on
WIN32 builds, when using these functions, would provide misleading
results.
In order to properly extend this support for all targets curl.h
would have to define curl_wcsdup_callback prototype and consequently
wchar_t should be visible before that in curl.h. IOW curl_wchar_t
defined in curlbuild.h and this pulling whatever system header is
required to get wchar_t definition.
Additionally a new curl_global_init_mem() function that also receives
user defined wcsdup() callback would be required.

HTTP proxy: insert slash in URL if missing
curl has been accepting URLs using slightly wrong syntax for a long
time, such as when completely missing as slash "http://example.org" or
missing a slash when a query part is given
"http://example.org?q=foobar".
curl would translate these into a legitimate HTTP request to servers,
although as was shown in bug #1206 it was not adjusted properly in the
cases where a HTTP proxy was used.
Test 1213 and 1214 were added to the test suite to verify this fix.
The test HTTP server was adjusted to allow us to specify test number in
the host name only without using any slashes in a given URL.
Multiple pipelines and limiting the number of connections.
Introducing a number of options to the multi interface that
allows for multiple pipelines to the same host, in order to
optimize the balance between the penalty for opening new
connections and the potential pipelining latency.
Two new options for limiting the number of connections:
CURLMOPT_MAX_HOST_CONNECTIONS - Limits the number of running connections
to the same host. When adding a handle that exceeds this limit,
that handle will be put in a pending state until another handle is
finished, so we can reuse the connection.
CURLMOPT_MAX_TOTAL_CONNECTIONS - Limits the number of connections in total.
When adding a handle that exceeds this limit,
that handle will be put in a pending state until another handle is
finished. The free connection will then be reused, if possible, or
closed if the pending handle can't reuse it.
Several new options for pipelining:
CURLMOPT_MAX_PIPELINE_LENGTH - Limits the pipeling length. If a
pipeline is "full" when a connection is to be reused, a new connection
will be opened if the CURLMOPT_MAX_xxx_CONNECTIONS limits allow it.
If not, the handle will be put in a pending state until a connection is
ready (either free or a pipe got shorter).
CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - A pipelined connection will not
be reused if it is currently processing a transfer with a content
length that is larger than this.
CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - A pipelined connection will not
be reused if it is currently processing a chunk larger than this.
CURLMOPT_PIPELINING_SITE_BL - A blacklist of hosts that don't allow
pipelining.
CURLMOPT_PIPELINING_SERVER_BL - A blacklist of server types that don't allow
pipelining.
