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

# `--json`
Sends the specified JSON data in a POST request to the HTTP server. --json
works as a shortcut for passing on these three options:
--data [arg]
--header "Content-Type: application/json"
--header "Accept: application/json"
There is **no verification** that the passed in data is actual JSON or that
the syntax is correct.
If you start the data with the letter @, the rest should be a file name to
read the data from, or a single dash (-) if you want curl to read the data
from stdin. Posting data from a file named 'foobar' would thus be done with
--json @foobar and to instead read the data from stdin, use --json @-.
If this option is used more than once on the same command line, the additional
data pieces are concatenated to the previous before sending.
The headers this option sets can be overridden with --header as usual.
