Simplify make files, add full dependencies.

#-------------------------------------------------------------------------

Add distprep target to take some of the job of the release_prep script. The latter updated accordingly. Also add `dist' and `distcheck' targets to play with, but caveat packager. Updated backend/bootstrap and backend/parser makefile to make them marginally builddir aware and fix the usual set of things. Add rule to automatically remake config.h dependent on config.h.in and config.status. (Adopted from Autoconf manual and about every other package.) On a good day we should now have a complete and accurate set of dependencies throughout everything.

Fix a few places where we needed -I. in CPPFLAGS to work properly in VPATH builds. We had this already in several places, but not all.

override CPPFLAGS := -I. -I$(srcdir) $(CPPFLAGS)
Arrange to compile flex output files as inclusions into other files (usually bison output files), not as standalone files. This hack works around flex's insistence on including <stdio.h> before we are able to include postgres.h; postgres.h will already be read before the compiler starts to read the flex output file. Needed for largefile support on some platforms.

Implement parser hooks for processing ColumnRef and ParamRef nodes, as per my recent proposal. As proof of concept, remove knowledge of Params from the core parser, arranging for them to be handled entirely by parser hook functions. It turns out we need an additional hook for that --- I had forgotten about the code that handles inferring a parameter's type from context. This is a preliminary step towards letting plpgsql handle its variables through parser hooks. Additional work remains to be done to expose the facility through SPI, but I think this is all the changes needed in the core parser.

Revise collation derivation method and expression-tree representation. All expression nodes now have an explicit output-collation field, unless they are known to only return a noncollatable data type (such as boolean or record). Also, nodes that can invoke collation-aware functions store a separate field that is the collation value to pass to the function. This avoids confusion that arises when a function has collatable inputs and noncollatable output type, or vice versa. Also, replace the parser's on-the-fly collation assignment method with a post-pass over the completed expression tree. This allows us to use a more complex (and hopefully more nearly spec-compliant) assignment rule without paying for it in extra storage in every expression node. Fix assorted bugs in the planner's handling of collations by making collation one of the defining properties of an EquivalenceClass and by converting CollateExprs into discardable RelabelType nodes during expression preprocessing.

Add makefile rules to check for backtracking in backend and psql lexers. Per discussion, we should enforce the policy of "no backtracking" in these performance-sensitive scanners.

FLEXFLAGS = -CF -b -p -p
Scanner performance improvements Use flex flags -CF. Pass the to-be-scanned string around as StringInfo type, to avoid querying the length repeatedly. Clean up some code and remove lex-compatibility cruft. Escape backslash sequences inline. Use flex-provided yy_scan_buffer() function to set up input, rather than using myinput().

# There is no correct way to write a rule that generates two files.
# Rules with two targets don't have that meaning, they are merely

gram.c: gram.y
Run check_keywords.pl anytime gram.c is rebuilt. This script is a bit slow, but still it only takes a fraction of the time the bison run does, so the overhead doesn't seem intolerable. And we definitely need some mechanical aid here, because people keep missing the need to add new keywords to the appropriate keyword-list production. While at it, I moved check_keywords.pl from src/tools into src/backend/parser where it's actually used, and did some very minor cleanup on the script.
