docs: make each libcurl man specify protocol(s)

The mandatory header now has a mandatory list of protocols for which the
manpage is relevant.

Most man pages already has a "PROTOCOLS" section, but this introduces a
stricter way to specify the relevant protocols.

cd2nroff verifies that at least one protocol is mentioned (which can be
`*`).

This information is not used just yet, but A) the PROTOCOLS section can
now instead get generated and get a unified wording across all manpages
and B) this allows us to more reliably filter/search for protocol
specific manpages/options.

Closes #13166

NAME

CURLOPT_INFILESIZE - size of the input file to send off

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE, long filesize);

DESCRIPTION

When uploading a file to a remote site, filesize should be used to tell libcurl what the expected size of the input file is. This value must be passed as a long. See also CURLOPT_INFILESIZE_LARGE(3) for sending files larger than 2GB.

For uploading using SCP, this option or CURLOPT_INFILESIZE_LARGE(3) is mandatory.

To unset this value again, set it to -1.

Using CURLOPT_UPLOAD(3) to an HTTP/1.1 server and this value set to -1, makes libcurl do a chunked transfer-encoded upload.

When sending emails using SMTP, this command can be used to specify the optional SIZE parameter for the MAIL FROM command.

This option does not limit how much data libcurl actually sends, as that is controlled entirely by what the read callback returns, but telling one value and sending a different amount may lead to errors.

EXAMPLE


#define FILE_SIZE 12345L

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    long uploadsize = FILE_SIZE;

    curl_easy_setopt(curl, CURLOPT_URL,
                     "ftp://example.com/destination.tar.gz");

    curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);

    curl_easy_setopt(curl, CURLOPT_INFILESIZE, uploadsize);

    curl_easy_perform(curl);
  }
}

AVAILABILITY

SMTP support added in 7.23.0

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
