Support Metalink.

This change adds experimental Metalink support to curl.
To enable Metalink support, run configure with --with-libmetalink.
To feed Metalink file to curl, use --metalink option like this:

$ curl -O --metalink foo.metalink

We use libmetalink to parse Metalink files.

Made -D option work with -O and -J.

To achieve this, first new structure HeaderData is defined to hold
necessary data to perform header-related work. Then tool_header_cb now
receives HeaderData pointer as userdata. All header-related work
(currently, dumping header and Content-Disposition inspection) are done
in this callback function. HeaderData.outs->config is used to determine
whether each work is done.

Unit tests were also updated because after this change, curl code always
sets CURLOPT_HEADERFUNCTION and CURLOPT_HEADERDATA.

Tested with -O -J -D, -O -J -i and -O -J -D -i and all worked fine.

curl tool: use configuration files from lib directory

Configuration files such as curl_config.h and all config-*.h no longer exist
nor are generated/copied into 'src' directory, now these only exist in 'lib'
directory from where curl tool sources uses them.

Additionally old src/setup.h has been refactored into src/tool_setup.h which
now pulls lib/setup.h

The possibility of a makefile needing an include path adjustment exists.

Generate lists and use symbols in --libcurl code output.

This patch improves the output of curl's --libcurl option by
generating code which builds curl_httppost and curl_slist lists, and
uses symbolic names for enum and flag values. Variants of the
my_setopt macro in tool_setopt.h are added in order to pass extra type
information to the code-generation step in tool_setopt.c.

If curl is configured with --disable-libcurl-option then the macros
call curl_easy_setopt directly.

curl tool: don't abort glob-loop due to failures

We want to continue to the next URL to try even on failures returned
from libcurl. This makes -f with ranges still get subsequent URLs even
if occasional ones return error. This was a regression as it used to
work and broke in the 7.23.0 release.

Added test case 1328 to verify the fix.

A regression between 7.22.0 and 7.23.0 -- downloading a file with the

only if there was no Content-Disposition header in the http response. If
there is a C-D header with a filename attribute, the output is correctly
written.

Previously we required that -S/--show-error was used _after_

Now, you can use them in any order and the result should still be the
same.
