docs/libcurl: generate PROTOCOLS from meta-data
Remove the PROTOCOLS section from the source files completely and
instead generate them based on the header data in the curldown files.

It also generates TLS backend information for options marked for TLS as
protocol.

# 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.
