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

# `--ipfs-gateway`
Specify which gateway to use for IPFS and IPNS URLs. Not specifying this will
instead make curl check if the IPFS_GATEWAY environment variable is set, or if
a `~/.ipfs/gateway` file holding the gateway URL exists.
If you run a local IPFS node, this gateway is by default available under
`http://localhost:8080`. A full example URL would look like:
curl --ipfs-gateway http://localhost:8080 ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi
There are many public IPFS gateways. See for example:
https://ipfs.github.io/public-gateway-checker/
WARNING: If you opt to go for a remote gateway you should be aware that you
completely trust the gateway. This is fine in local gateways as you host it
yourself. With remote gateways there could potentially be a malicious actor
returning you data that does not match the request you made, inspect or even
interfere with the request. You will not notice this when using curl. A
mitigation could be to go for a "trustless" gateway. This means you locally
verify that the data. Consult the docs page on trusted vs trustless:
