This series makes genksyms remember the values of enum constants and use them
during symbol expansion. This makes sure that patches like

| enum e {
|  	E1,
| 	E2,
|+	E3,
| 	E_MAX
| };
|
| struct s {
| 	int a[E_MAX];
| }
|
| int f(struct s *s) { ... }
| EXPORT_SYMBOL(f)

change the checksum of the exported symbol. Previously, it would just use the
string "E_MAX" in the calculation and the change would go unnoticed. The main
part is in patches 6/7 and 7/7, the rest are cleanups and preparatory patches.

The header is already #included, no need to include it a second time.
lex.c_shipped was regenerated using flex-2.5.35.

Instead of special-casing SYM_NORMAL, do not map any name to it. Also
explicitly set the single-letter name of the symbol type, which will be
needed by a further patch. The only user-visible change is one debug
printf.

Allow searching for symbols of an exact type. The lexer does this and a
subsequent patch will add one more usage.

Enum constants can be used as array sizes; if the enum itself does not
appear in the symbol expansion, a change in the enum constant will go
unnoticed. Therefore, remember the value of each enum constant and
expand each occurence to <constant> <value>.

Note: The changes won't take effect until the lexer and parser are
rebuilt by the next patch.

Hi Michal.

Patch serie looks good.
You can add my ack to all of them if you do a second round.

This nice explanation would be good to include in the changelog
of 7/8 so "git log" give a better intro to the changes.
