docs/cmdline: change to .md for cmdline docs
- switch all invidual files documenting command line options into .md,
   as the documentation is now markdown-looking.

 - made the parser treat 4-space indents as quotes

 - switch to building the curl.1 manpage using the "mainpage.idx" file,
   which lists the files to include to generate it, instead of using the
   previous page-footer/headers. Also, those files are now also .md
   ones, using the same format. I gave them underscore prefixes to make
   them sort separately:
   _NAME.md, _SYNOPSIS.md, _DESCRIPTION.md, _URL.md, _GLOBBING.md,
   _VARIABLES.md, _OUTPUT.md, _PROTOCOLS.md, _PROGRESS.md, _VERSION.md,
   _OPTIONS.md, _FILES.md, _ENVIRONMENT.md, _PROXYPREFIX.md,
   _EXITCODES.md, _BUGS.md, _AUTHORS.md, _WWW.md, _SEEALSO.md

 - updated test cases accordingly

Closes #12751

# `--fail`
Fail fast with no output at all on server errors. This is useful to enable
scripts and users to better deal with failed attempts. In normal cases when an
HTTP server fails to deliver a document, it returns an HTML document stating
so (which often also describes why and more). This flag prevents curl from
outputting that and return error 22.
This method is not fail-safe and there are occasions where non-successful
response codes slip through, especially when authentication is involved
(response codes 401 and 407).
