logging: remove unused message-id scriptsv3.5.1beta

The current unused implementation for message-ids in the logs depends on
automatically generated files. The generated files are not included in
the distributed tarball. This causes issues when distributions build
packages, they need to re-run ./autogen.sh to create the needed files.

I thought of including the generated files in the distribution tarball.
However, the contents of these files are not actively used, so it seems
to make more sense to drop it all together. These functions were the
only users of libintl and gettext too, so dropped the requirement
checking from configure.ac.

A replacement for the message-id logging framework is in progress. Any
changes that this patch makes, can be reverted in the submission of
patches for the new framework.

-New logging framework in glusterfs is targeted for end users like
-customers, community members, testers etc.  This aims to bring clear,
-understandable logs called user logs whereas the current logging are
-considered as developer logs.  The new framework brings with following
-features
-
-* Each message is logged with proper well defined error code and each
-  error code has well known error message.
-* A logbook has defined error code and error messages.  It helps to
-  keep track of possible causes and remedies
-* Log are sent to syslog.  The syslog application can be configured to
-  pass them to centralized logging system
-* It brings
-  - Remove repeated log messages
-  - Send alerts to users on certain events
-  - Run a program on events
-  - Call home service on events
-
-
-Log book:
-=========
-A log book is a JSON formatted file error-codes.json located in top
-level of glusterfs source repository.  At compile time, gen-headers.py
-generates libglusterfs/src/gf-error-codes.h using the log book and
-gf-error-codes.h.template file.  libglusterfs/src/gf-error-codes.h
-consists of header definitions and helper functions to get message by
-code for given locale. Currently it has _gf_get_message() function
-returns message for locale 'en'.
-
-New entry to log book is added like
-
-{
-    "IO_ERROR": {"code": 2233,
-                 "message": {"en": "I/O error occurred"}},
-    "SETUP_ERROR": {"code": 2240,
-                 "message": {"en": "Setup error"}},
-}
-
-
-Logging:
-========
-The framework provides two functions
-
-void gf_openlog (const char *ident, int option, int facility);
-void gf_syslog (int error_code, int facility_priority, char *format, ...);
-
-Consumers need to call gf_openlog() prior to gf_syslog() like the way
-traditional syslog function calls.  error_code is mandatory when using
-gf_syslog().  For example,
-
-gf_openlog (NULL, -1, -1);
-gf_syslog (GF_ERR_DEV, LOG_ERR, "error reading configuration file");
-
-The logs are sent in CEE format (http://cee.mitre.org/) to syslog.
-Its targeted to rsyslog syslog server.
-
-This log framework is enabled at compile time by default.  This can be
-disabled by passing '--disable-syslog' to ./configure or '--without
-syslog' to rpmbuild
-
-Even though its enabled at compile time, its required to have
-/etc/glusterfs/logger.conf file to make it into effect before starting
-gluster services
-
-Currently all gluster logs are sent with error code GF_ERR_DEV.
