The main motivation for this is that it's required for Informix compatibility
in ECPG.
This patch makes the ECPG and core grammars a bit closer to one another for
these productions.

it works just as well to have them be ordinary identifiers, and this gets rid
of a number of ugly special cases. Plus we aren't interfering with non-rule
usage of these names.
catversion bump because the names change internally in stored rules.
to create a function for it.
Procedural languages now have an additional entry point, namely a function
to execute an inline code block. This seemed a better design than trying
to hide the transient-ness of the code from the PL. As of this patch, only
plpgsql has an inline handler, but probably people will soon write handlers
for the other standard PLs.
In passing, remove the long-dead LANCOMPILER option of CREATE LANGUAGE.

It seems the flex developers have decided to change yyleng from int to size_t.
This has already happened in the latest release of OS X, and will start
happening elsewhere once the next release of flex appears. Rather than trying
to divine how it's declared in any particular build, let's just remove the one
existing not-very-necessary external usage.
Back-patch to all supported branches; not so much because users in the field
are likely to care about building old branches with cutting-edge flex, as
to keep OSX-based buildfarm members from having problems with old branches.
source directory even for out-of-tree builds. They are now alsl built in
the build tree. This should be more convenient for certain developers'
workflows, and shouldn't really break anything else.
Update install-sh to that from Autoconf 2.63, plus our Darwin-specific
changes (which I simplified a bit). install-sh is now able to install
multiple files in one run, so we could simplify our makefiles sometime.
install-sh also now has a -d option to create directories, so we don't need
mkinstalldirs anymore.
Use AC_PROG_MKDIR_P in configure.in, so we can use mkdir -p when available
instead of install-sh -d. For consistency with the rest of the world,
the corresponding make variable has been renamed from $(mkinstalldirs) to
$(MKDIR_P).
Test coverage support now covers the entire source tree, including
contrib, instead of just src/backend. In a related but independent
development, the commands make coverage and make coverage-html can be run
in any directory.
This turned out to be much easier than feared. Besides a few ad hoc fixes
to pass the make target down the tree, change all affected makefiles to
list their directories in the SUBDIRS variable, changed from variants like
DIRS and WANTED_DIRS. MSVC build fix was attempted as well.
Both hex format and the traditional "escape" format are automatically
handled on input. The output format is selected by the new GUC variable
bytea_output.
As committed, bytea_output defaults to HEX, which is an *incompatible
change*. We will keep it this way for awhile for testing purposes, but
should consider whether to switch to the more backwards-compatible
default of ESCAPE before 8.5 is released.

values being complained of.
In passing, also remove the arbitrary length limitation in the similar
error detail message for foreign key violations.

sockopt(SO_NOSIGPIPE) or the MSG_NOSIGNAL flag to send().
We assume these features are available if (1) the symbol is defined at
compile time and (2) the kernel doesn't reject the call at runtime.
It might turn out that there are some platforms where (1) and (2) are
true and yet the signal isn't really blocked, in which case applications
would die on server crash. If that sort of thing gets reported, then
we'll have to add additional defenses of some kind.

Changes:
Pass in the keyword lookup array instead of having it be hardwired.
(This incidentally allows elimination of some duplicate coding in ecpg.)
Re-order the token declarations in gram.y so that non-keyword tokens have
numbers that won't change when keywords are added or removed.
Add ".." and ":=" to the set of tokens recognized by scan.l. (Since these
combinations are nowhere legal in core SQL, this does not change anything
except the precise wording of the error you get when you write this.)
__attribute__() marker so that gcc can validate the format string against
the actual arguments, get rid of overcomplicated and unsafe usage in
base_yyerror().
