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.

reverts unreleased invalid memory leak fix

More changes, bugfixes and contributors!

Proxy servers tend to add their own headers at the beginning of
responses. The size of these headers was not taken into account by
CURLINFO_HEADER_SIZE before this change.

Bug: http://curl.haxx.se/bug/view.cgi?id=1204

Corrected some incorrectly positioned pointer variable declarations to
be "char *" rather than "char* ".

Corrected some incorrectly positioned pointer variable declarations to
be "type *" rather than "type* ".

Updated the reply data in tests: 800, 801, 802, 804 and 1321 to possess
the CRLF as per RFC-822.

This patch removes building curlbuild.h from the build_vms.com procedure
and uses the one in the daily or release tarball instead.

packages/vms/build_curlbuild_h.com is obsolete with this change.

Accessing the library module name "tool_main" needs different handling
when the optional extended parsing is enabled.

Tested on IA64/VMS 8.4 and VAX/VMS 7.3

I found out that ECC doesn't work as of OS X 10.8.3, so those ciphers are
turned off until the next point release of OS X.

After having done a POST over a CONNECT request, the 'rewindaftersend'
boolean could be holding the previous value which could lead to badness.

This should be tested for in a new test case!

Bug: https://groups.google.com/d/msg/msysgit/B31LNftR4BI/KhRTz0iuGmUJ

Moved SMTP, POP3, IMAP and New Protocol sections to be listed after the
other protocols (FTP, HTTP and TELNET) and SASL to be after SSL and
GnuTLS as these are all security related.

Additionally fixed numbering of the SSL and GnuTLS sections as they
weren't consecutive.

Fixed incorrect initial response generation for the NTLM and LOGIN SASL
authentication mechanisms when the SASL-IR was detected.

Introduced in commit: 6da7dc02.

These verfy that the 'memory tracking' subsystem is actually doing its
job when using curl tool (#96), a test in libtest (#558) and also a unit
test (#1330), in order to prevent regressions in this functionallity.

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.

Bug: http://curl.haxx.se/bug/view.cgi?id=1206
Reported by: ScottJi

Used hard coded data from RFC-3501 section 6.3.2.

This commit alone does not fix anything nor modifies existing
interfaces or behaviors, although it is a prerequisite for other
fixes.

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.

See the curl_multi_setopt() man page for details.

vms_show 'extern' storage-class specifier removed from tool_main.c due to...

- Advice from Tor Arntsen: http://curl.haxx.se/mail/lib-2013-03/0164.html

- HP OpenVMS docs stating that 'Extern is the default storage class for
  variables declared outside a function.'
  http://h71000.www7.hp.com/commercial/c/docs/dec_c_help_5.html
  (Storage_Classes section)

Following commit e450f66a and the changes in the multi interface
being used internally, from 7.29.0, the transfer cancellation in
pop3_dophase_done() is no longer required.

Added missing slash in cc_full_list.
Removed unwanted extra quotes inside symbol tool_main
for non-VAX architectures that triggered link failure.
Replaced curl_sys_inc with sys_inc.
