Catch up with all the lint warnings since exit on warning was disabled.
Disable 'missing header declaration' and 'nested extern' warnings for now.

__dberr: tweak signature to make gcc8 -Wbad-function-cast happy about
casts in __dbpanic. Admittedly this is a bit too "cute".

__dbpanic: use the official DB typedef name in the casts. They were
copied from the declaration point where it's not yet available.

Fix the build for ancient (rhel5) systems that don't have O_CLOEXEC

whitelist O_CLOEXEC flag, should fix lastlogin issue.

Consistently include "nbtool_config.h" when cross-compiling.

In preparation for providing a db fallback in libnbcompat, remove
sccsid and conditionals around __RCSID. lint understands __RCSID enough
to ignore it, undefining LIBC_SCCS is superseded by MKSTRIPIDENT.
No functional changes.

branches: 1.14.12;
cleanup:
- remove __P
- remove unneeded casts
- add _DIAGASSERT
- add more diagnostics for integer overflow
- fix size_t/int confusion
- make debugging and statistics code compile

Move UCB-licensed code from 4-clause to 3-clause licence.

Delint.
Remove trailing ; from uses of __weak_alias(). The macro inserts this if
needed.

delint

Change the file mode argument to dbopen() and the db backends from int to
mode_t.

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.

This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
