WINSOCK only:
Since FD_CLOSE is only signaled once, it may trigger at the same
time as FD_READ. Data actually being available makes it impossible
to detect that the connection was closed by checking that recv returns
zero. Another recv attempt could block the connection if it was
not closed. This workaround abuses exceptfds in conjunction with
readfds to signal that the connection has actually closed.
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.
The new read and write wrapper functions support reading from stdin
and writing to stdout/stderr on Windows by using the appropriate
Windows API functions and data types.
Modified sws to support and use custom CONNECT responses instead of the
previously naive hard-coded version. Made the HTTP test server able to
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.
Adapted a larger amount of tests to the new <connect> style.

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.
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.

This commit renames lib/setup.h to lib/curl_setup.h and
renames lib/setup_once.h to lib/curl_setup_once.h.
Removes the need and usage of a header inclusion guard foreign
to libcurl. [1]
Removes the need and presence of an alarming notice we carried
in old setup_once.h [2]
----------------------------------------
1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard
up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H,
this single inclusion guard is enough to ensure that inclusion of
lib/setup_once.h done from lib/setup.h is only done once.
Additionally lib/setup.h has always used __SETUP_ONCE_H macro to
protect inclusion of setup_once.h even after commit ec691ca3, this
was to avoid a circular header inclusion triggered when building a
c-ares enabled version with c-ares sources available which also has
a setup_once.h header. Commit ec691ca3 exposes the real nature of
__SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard
foreign to libcurl belonging to c-ares's setup_once.h
The renaming this commit does, fixes the circular header inclusion,
and as such removes the need and usage of a header inclusion guard
foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl.
2 - Due to the circular interdependency of old lib/setup_once.h and the
c-ares setup_once.h header, old file lib/setup_once.h has carried
back from 2006 up to now days an alarming and prominent notice about
the need of keeping libcurl's and c-ares's setup_once.h in sync.
Given that this commit fixes the circular interdependency, the need
and presence of mentioned notice is removed.
All mentioned interdependencies come back from now old days when
the c-ares project lived inside a curl subdirectory. This commit
removes last traces of such fact.
This commit fixes support for sockets that are ready to accept
a new connection and have previously been put into listening mode.
It also includes changes which are the result of investigation
regarding Windows STDIN. These changes are the preparation for further
improvements regarding support for reading data from STDIN on Windows.
Open issue: WaitForMultipleObjectsEx does not support PIPE handles
which are returned by GetStdHandle while running without a GUI.

WinSock select() does not support standard file descriptors,
it can only check SOCKETs. The following function is an attempt
to create a select() function with support for other handles.
BLANK_AT_MAKETIME may be used in our Makefile.am files to blank
LIBS variable used in generated makefile at makefile processing
time. Doing this functionally prevents LIBS from being used for
all link targets in given makefile.
Since automake 1.12.4, the warnings are issued on running automake:
warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
Avoid INCLUDES and roll these flags into AM_CPPFLAGS.
Compile tested on:
Ubuntu 10.04 (automake 1:1.11.1-1)

Fix a bug where closed sockets (fd -1) were left in the all_sockets
list, because of missing parens in a pointer arithmetic expression
Reenable the tests that were locking up due to this bug.
SO_KEEPALIVE flag to all sockets. Note that several loops which used to continue on a return value
of 0 (theoretical since 0 would never be returned without O_NONBLOCK) now break on 0 so that they
won't continue reading until after poll is called again.
for non-blocking sockets: now -1 means error or connection finished, 1 means data was read, and 0
means there is no data available now so need to wait for poll (new return value)
half-finished.
Note the the req struct used to be re-initialized AFTER reading pipeline data, so now that we
initialize it from the caller we must be careful not to overwrite the pipeline data.
Also we now need to handle the case where the buffer is already full when get_request is called -
previously this never happened as it was always called with an empty buffer and looped until done.
Now get_request is called in a loop, so the next step is to run the loop on a socket only when poll
signals it is readable.
