curldown: fixups
- make DEFAULT sections less repetitive

- make historic mentions use HISTORY

- generate the protocols section on `# %PROTOCOLS%` instead of guessing
  where to put it

- generate the availability section on `# %AVAILABILITY%` instead of
  guessing where to put it

- make the protocols section more verbose

Closes #14227

# NAME
CURLOPT_TLSAUTH_USERNAME - username to use for TLS authentication
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TLSAUTH_USERNAME, char *user);
~~~
# DESCRIPTION
Pass a char pointer as parameter, which should point to the null-terminated
username to use for the TLS authentication method specified with the
CURLOPT_TLSAUTH_TYPE(3) option. Requires that the CURLOPT_TLSAUTH_PASSWORD(3)
option also be set.
The application does not have to keep the string around after setting this
option.
This feature relies on TLS SRP which does not work with TLS 1.3.
# DEFAULT
NULL
# %PROTOCOLS%
# EXAMPLE
~~~c
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_TLSAUTH_TYPE, "SRP");
curl_easy_setopt(curl, CURLOPT_TLSAUTH_USERNAME, "user");
curl_easy_setopt(curl, CURLOPT_TLSAUTH_PASSWORD, "secret");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
~~~
# %AVAILABILITY%
# RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
