d1d003c232 buffer: use ssh_buffer_get() instead of ssh_buffer_get_begin() 
This commit is a preparatory stage for removing ssh_buffer_get_begin().
Note that removing ssh_buffer_get_begin() doesn't break API
compatibility, as this functions has never been exposed (it only has the
LIBSSH_API prefix).

05fd0acf45 buffer: do not use ssh_buffer_get_rest_len() 
As ssh_buffer_get_len() actually calls ssh_buffer_get_rest_len(), let's
just use the first one. This is a preparatory step for removing
ssh_buffer_get_rest_len().

adc8c20ac1 cleanup: use ssh_ prefix in the buffer (non-static) functions 
Having "ssh_" prefix in the functions' name will avoid possible clashes
when compiling libssh statically.

bdfe6870f6 pki: Add certificate loading functions 
- ssh_pki_import_cert_base64()
- ssh_pki_import_cert_file()
- ssh_pki_import_cert_blob()
Those functions are currently simple wrappers around their pubkey counterpart.

- ssh_pki_copy_cert_to_privkey()
This function copies the cert-specific data to a private key.
