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
curl_share_init - Create a shared object
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLSH *curl_share_init();
~~~
# DESCRIPTION
This function returns a pointer to a *CURLSH* handle to be used as input
to all the other share-functions, sometimes referred to as a share handle in
some places in the documentation. This init call MUST have a corresponding
call to curl_share_cleanup(3) when all operations using the share are
complete.
This *share handle* is what you pass to curl using the
CURLOPT_SHARE(3) option with curl_easy_setopt(3), to make that
specific curl handle use the data in this share.
# EXAMPLE
~~~c
int main(void)
{
CURLSHcode sh;
CURLSH *share = curl_share_init();
sh = curl_share_setopt(share, CURLSHOPT_SHARE, CURL_LOCK_DATA_CONNECT);
if(sh)
printf("Error: %s\n", curl_share_strerror(sh));
}
~~~
# AVAILABILITY
Added in 7.10
# RETURN VALUE
If this function returns NULL, something went wrong (out of memory, etc.)
and therefore the share object was not created.
