db: fix lint warnings about wrong call to ctype functions

sync with head

The "-N" command line option means "include the terminating NUL byte",
so rename the corresponding flag from F_NO_NUL to F_INCLUDE_NUL to match
the behaviour.

This is the second half of the fix for PR 46035.

	usr.bin/db/db.c: revision 1.24
Rework how reading keys functions so that key lookups from hash databases
works again.  (I accidentally broke that in rev 1.15)
Fixes problem noted by Masao Uebayashi.

fix -Wsign-compare issues

Explicitly pull in "nbtool_config.h" if available.
Fixes tools/db build, as reported by Matthias Scheler.

Fail with a non-zero exit code if deleting a non-existant key.
Fixes bug introduced in rev 1.15, and reported in PR 39710 from Juan RP.

Don't display various warnings in delete if -q.
Suggested in PR 39710.

Add some sanity enforcing abort()s.

Sync with wrstuden-revivesa-base-2.

Add -P pagesize, to tune the btree psize and hash bsize.
Set to 0 to let the system choose (based on st_blksize of the file)
Defaults to 4096.

Support -Th (VIS_HTTPSTYLE) when -U decoding key/value for delete or write

Fix -N so that it sets O_TRUNC in the flags to pass to dbopen(3)
and not the flags used by db(1) to control internal behaviour.

Support -Th to enable VIS_HTTPSTYLE.
Expand description of -T so there's less need to consult
both vis(1) and strvis(3) to determine what the characters mean.

sync with head.

Remove clause 3 and 4 from TNF licenses

* Support reading multiple keys with the same name if '-D' is given,
  using db->seq() and match comparison rather than db->get().
* Deleting multiple keys of the same name appears to already work as-is
  with a single db->del() call; I had code to implement this if '-D'
  is given but it appears to be unnecessary.
* Cosmetic/KNF tweaks.

Allow the input [file] field separator to be a string and not just a
single character.
Use argument-specific value names in the usage string & manual page
to simplify searching for the value's use.

Pull up revision 1.13 (requested by seb in ticket #1142):
When vis encoding with -S, only remove the trailing NUL if -N isn't used and
the item's size is > 0.

When vis encoding with -S, only remove the trailing NUL if -N isn't used and
the item's size is > 0.

Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

safer use of realloc

add missing #ifdef __RCSID
(these files are compiled as host tools)
from Nicolas Ollinger, fixes PR#21892

Sync usage with man page; break to 80 chars/line.

Add option -S to specify strvis(3) encoding of keys and/or values
when reading a database.  Add options -T and -X to tweak encoding.

Add option -U to specify strunvis(3) decoding of keys and/or values
when writing a database or deleting entries from a database.

Kill TODO item 'add option to strunvis(3) key (& value) from infile
?': unvis(1) can be used to achieve that.

Approved by lukem@. And thanks to him for suggestions.

Fix usage message and SYNOPSIS section wrt to option O as suggested by wiz.

After discussion with lukem rename 's' option to 'O'.
Hopefully 's' option has been here only a couple of hours.

Fix error message for option `F' when passed a bogus argument.
Actually activate option `F' in getopt's optstring.
Implement option `s' to specify output field separator string.

Approved by lukem.

fix  -E endian

some todo items

- set cachesize to 1MB (instead of default 2.5KB); greatly improves
  performance on large imports
- remove unnecessary asserts

db(1) - manipulate db(3)'s btree(3) and hash(3) databases
