David Michmerhuizen created an issue: https://gitlab.com/gnutls/gnutls/-/issues/1025

## Description of problem:

The documentation for gnutls_x509_crt_export2 claims that 

"In case of failure a negative error code will be returned, and 0 on success."

This is incorrect, as the value of _gnutls_fbase64_encode is sometimes directly returned, which is the length of the exported certificate.  Specifically, 0 or greater is returned on success. 

## Version of gnutls used:


## Distributor of gnutls (e.g., Ubuntu, Fedora, RHEL)
