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

CURLINFO_EFFECTIVE_METHOD - get the last used HTTP method

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_EFFECTIVE_METHOD,
                           char **methodp);

DESCRIPTION

Pass in a pointer to a char pointer and get the last used effective HTTP method.

In cases when you have asked libcurl to follow redirects, the method may not be the same method the first request would use.

The methodp pointer is NULL or points to private memory. You MUST NOT free - it gets freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.

PROTOCOLS

HTTP(S)

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "data");
    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
    res = curl_easy_perform(curl);
    if(res == CURLE_OK) {
      char *method = NULL;
      curl_easy_getinfo(curl, CURLINFO_EFFECTIVE_METHOD, &method);
      if(method)
        printf("Redirected to method: %s\n", method);
    }
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY

Added in 7.72.0

RETURN VALUE

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