Previously it would access a NULL pointer and die.

Only <curl/curl.h> is needed typically and curl/types.h has been removed

CURLM_CALL_MULTI_PERFORM stopped being a valid return code from
curl_multi_perform back in 7.20.0. All the libcurl tests are ajusted to
this and no longer check for this return code. Makes them simpler.

Autobuild submitters can use this to add some text to their
setup files to describe issues they've found with the build
or tests. This could include laying blame on test failures on
network issues or dependent libraries, explaining away compiler
warnings or providing any additional information that could be
useful to people reviewing and investigating problems with the
publicly available autobuild logs.  Note that persistent test
failures that are not issues with curl itself should normally be
fixed by excluding them from the test run instead.

This is an entirely optional field that is not entered by the
user the first time a new build is created.

Just to make sure a user is aware of it.

This is a security flaw. See curl advisory 20110623 for details.

[pop3] remove extra space in LIST command

Some servers, e.g. mail.bezeqint.net:110, consider it a syntax error

compiler warning: conditional expression is constant

compiler warning: variable is initialized but not referenced

adding unit test for Curl_llist_move, documenting unit-tested functions
in llist.c, changing unit-test to unittest, replacing assert calls with
abort_unless calls

The CURLFORM_STREAM is documented to only insert a file name (and thus
look like a file upload) in the part if CURLFORM_FILENAME is set, but in
reality it always inserted a filename="" and if CURLFORM_FILENAME wasn't
set, it would insert insert rubbish (or possibly crash).

This is now fixed to work as documented, and test 554 has been extended
to verify this.

Bug: http://curl.haxx.se/mail/lib-2011-06/0070.html

Properly deal with the fact that the last fread() call most probably is
a short read, and when using callbacks in fact all calls can be short
reads. No longer consider a file read done until it returns a 0 from the
read function.

Bug: http://curl.haxx.se/mail/lib-2011-06/0048.html

If a piece is set to use a callback to get the data, it should not be
treated as data. It unfortunately also requires that curl_easy_perform()
or similar has been used as otherwise the callback function hasn't been
figured out and curl_formget won't know how to get the content.

Due to a design flaw, the CURLFORM_STREAM option doesn't really work
with curl_formget until after curl_easy_perform (or similar).

We don't author the bindings, they are created outside the main project.

These were just warnings in test code but it still makes it nicer to not
generate them.

Typecast when converting to int from long to avoid some compiler warnings

Removing dynamic allocations also simplifies the test.
