Various fixes for log message tags:

- Remove tags in ssl_log_ssl_error() and ssl_log_cert_error()
- Instead add tags to various ssl_log_xerror, ssl_log_cxerror
  calls (ssl_log_rxerror is unused).
- likewise for modssl_proxy_info_log()

- Fix spelling of APLOG_NOERRNO in coccinelle script
- add support for ssl_log_*error and ap_log_cserror

- add some more tags missing due to APLOG_NOERRNO spelling error

- Remove tags from example modules (we don't want people to blindly copy
  those)
