docs: introduce "curldown" for libcurl man page format
curldown is this new file format for libcurl man pages. It is markdown
inspired with differences:

- Each file has a set of leading headers with meta-data
- Supports a small subset of markdown
- Uses .md file extensions for editors/IDE/GitHub to treat them nicely
- Generates man pages very similar to the previous ones
- Generates man pages that still convert nicely to HTML on the website
- Detects and highlights mentions of curl symbols automatically (when
  their man page section is specified)

tools:

- cd2nroff: converts from curldown to nroff man page
- nroff2cd: convert an (old) nroff man page to curldown
- cdall: convert many nroff pages to curldown versions
- cd2cd: verifies and updates a curldown to latest curldown

This setup generates .3 versions of all the curldown versions at build time.

CI:

Since the documentation is now technically markdown in the eyes of many
things, the CI runs many more tests and checks on this documentation,
including proselint, link checkers and tests that make sure we capitalize the
first letter after a period...

# NAME
CURLOPT_PREQUOTE - commands to run before an FTP transfer
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREQUOTE,
struct curl_slist *cmds);
~~~
# DESCRIPTION
Pass a pointer to a linked list of FTP commands to pass to the server after
the transfer type is set. The linked list should be a fully valid list of
struct curl_slist structs properly filled in as described for
CURLOPT_QUOTE(3). Disable this operation again by setting a NULL to this
option.
These commands are not performed when a directory listing is performed, only
for file transfers.
While CURLOPT_QUOTE(3) and CURLOPT_POSTQUOTE(3) work for SFTP,
this option does not.
# DEFAULT
NULL
# PROTOCOLS
FTP
# EXAMPLE
~~~c
int main(void)
{
struct curl_slist *cmdlist = NULL;
cmdlist = curl_slist_append(cmdlist, "SYST");
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");
/* pass in the FTP commands to run */
curl_easy_setopt(curl, CURLOPT_PREQUOTE, cmdlist);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
~~~
# AVAILABILITY
Along with the protocol support
# RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
