This makes it possible to increase the size of the buffers when needed
in later patches.  No functional change yet.

Instead of remembering before each "return" statement which temporary
allocations, if any, need to be freed, take care to set pointers to
NULL when no longer needed and use a goto to a common block to exit
the function and free all temporaries.

No functional change intended.  Currently the only temporary buffer in
this function is "proxy" which is already correctly freed when
appropriate, but there will be more soon.

Use appropriately sized buffers on the heap instead of fixed-size
buffers on the stack, to allow for longer usernames and passwords.

Callers never pass anything longer than MAX_CURL_USER_LENGTH (resp.
MAX_CURL_PASSWORD_LENGTH), so no functional change inteded yet.

Adding this line allows libcurl to return the server response when
performing a search command via a custom request.

The new multiply() function detects range value overflows. 32bit
machines will overflow on a 32bit boundary while 64bit hosts support
ranges up to the full 64 bit range.

Added test 1236 to verify.

A rather big overhaul and cleanup.

1 - curl wouldn't properly detect and reject globbing that ended with an
open brace if there were brackets or braces before it. Like "{}{" or
"[0-1]{"

2 - curl wouldn't properly reject empty lists so that "{}{}" would
result in curl getting (nil) strings in the output.

3 - By using strtoul() instead of sscanf() the code will now detected
over and underflows. It now also better parses the step argument to only
accept positive numbers and only step counters that is smaller than the
delta between the maximum and minimum numbers.

4 - By switching to unsigned longs instead of signed ints for the
counters, the max values for []-ranges are now very large (on 64bit
machines).

5 - Bumped the maximum number of globs in a single URL to 100 (from 10)

6 - Simplified the code somewhat and now it stores fixed strings as
single- entry lists. That's also one of the reasons why I did (5) as now
all strings between "globs" will take a slot in the array.

Added test 1234 and 1235 to verify. Updated test 87.

This commit fixes three separate bug reports.

Add the curl release notes to the release note document generated for
VMS packages.

Add the different filenames generated by a daily build to the
cleanup procedures.

... just to make them easier to print in debug ouputs while debugging.
They are still within #ifdef [debugbuild].

This makes the socket callback get called with the proper bitmask as
otherwise the application could be left hanging waiting for reading on
an upload connection!

... prior to calling PK11_GenerateRandom()

With everything being struct SessionHandle pointers now, this rename
makes multi.c use the library-wide practise of calling that pointer
'data' instead of the previously used 'easy'.

Moved Curl_easy_addmulti() from easy.c to multi.c, renamed it to
easy_addmulti and made it static.

Removed Curl_easy_initHandleData() and uses of it since it was emptied
in commit cdda92ab67b47d74a.

All protocol handler structs are now opaque (void *) in the
SessionHandle struct and moved in the request-specific sub-struct
'SingleRequest'. The intension is to keep the protocol specific
knowledge in their own dedicated source files [protocol].c etc.

There's some "leakage" where this policy is violated, to be addressed at
a later point in time.

1 - always allocate the struct in protocol->setup_connection. Some
protocol handlers had to get this function added.

2 - always free at the end of a request. This is also an attempt to keep
less memory in the handle after it is completed.

Start working on the next version and up some counters.

It shows intermittent failures and I haven't been able to track them
down yet. Disable this test for now.

The take down of the global dns cache didn't take CURLOPT_RESOLVE names
into account.

CURLOPT_DNS_USE_GLOBAL_CACHE broke in commit c4312741 (been
broken since the libcurl 7.29.0 release). While this option has been
documented as deprecated for almost a decade and nobody even reported
this bug, it should remain functional.

Added test case 1512 to verify

VMS modified files either missing from a previous commit and changes
to remove references to CVS repositories.

The previous naming scheme ftp_state_post_XXXX() wasn't really helpful
as it wasn't always immediately after 'xxxx' and it wasn't easy to
understand what it does based on such a name.

This new one is instead ftp_state_yyyy() where yyyy describes what it
does or sends.

Since the mk-ca-bundle tool itself isn't installed with make install,
there's no point in installing its documentation.

These are the files needed to build VMS distribution packages known as
PCSI kits.

Also minor update to the existing files, mainly to the documentation and
file clean up code.

This is the first version of this new document, detailing the seven
perhaps most important internal structs in libcurl source code:

  1.1 SessionHandle
  1.2 connectdata
  1.3 Curl_multi
  1.4 Curl_handler
  1.5 conncache
  1.6 Curl_share
  1.7 CookieInfo
