Gw.h contained a fair amount of obsolete function declarations,
duplicate declarations of functions declared in utils.h and
declarations of functions that conceptually are similar to those
in utils.h.
The obsolete and duplicate ones were removed and all but one of
the remaining moved to utils.h. Correspondingly the implementation
was moved from gw_utils.c to utils.c.
The one remaining function - gw_daemonize() - is not really worthy
of a file of its own, so that is to be moved to gateway.c after which
gw_utils.c can be removed.
Gw.h still contains defines that are duplicated in
maxscale/protocol/mysql.h. The ones in gw.h are to be removed. It
appears that the entire gw.h will disappear.
- STRERROR_BUFLEN moved to cdefs.h and renamed to MXS_STRERROR_BUFLEN.
Better would be to provide a 'const char* mxs_strerror(int errno)'
that would have a thread specific buffer for the error message.
- MIN and MAX also moved to defs.h as MXS_MIN and MXS_MAX.
- Now only mlist.h of the headers depend upon skygw_utils.h.
The purpose of this file is to provide a header that *must* be included
first (that is, also before any system headers) by all other headers. On
the one hand this file provides a place where compilation environment
dependent things can be defined, and, on the other hand, a place where
things can be redefined globally, should that be necessary for whatever
reason. It further provides a place where constants applicable across
the line can be defined.
