I am retiring my old email address; replace it with my OpenBSD one.

Use recallocarray() to avoid leaving detritus in memory when resizing
buffers. We don't bother doing this for objects containing pointers,
but focus on controllable data.
ok millert

Only reallocate the buffer to fit for medium-size allocations where
we expanded the buffer to a single page. The final realloc() can
be expensive for large buffers and is not realled needed. OK deraadt@

Use a macro for the initial length of the buffer instead of 127; OK deraadt@

Remove NULL-checks before free() and a few related dead assignments.

ok and valuable input from millert@

Add framework for resolving (pun intended) libc namespace issues, using
wrapper .h files and asm labels to let internal calls resolve directly and
not be overridable or use the PLT. Then, apply that framework to most of
the functions in stdio.h, string.h, err.h, and wchar.h. Delete the
should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here.

tests clean on i386, amd64, sparc64, powerpc, and mips64

All these files include <stdlib.h>, so do not need to cast
malloc/calloc/realloc* returns.

Fix the handle locking in stdio to use flockfile/funlockfile
internally when and where required. Macros in <stdio.h> are updated
to automatically call the underlying functions when the process is
threaded to obtain the necessary locking. A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization. Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.

committing on behalf of and okay guenther@ now that we have install
media space available.

Back out previous commit, as it caused too much growth for the install
media to fit

ok kurt@, earlier version tested by sthen@ and jj@

Adapt things to use __type_t instead of _BSD_TYPE_T_
Add new sys/_types.h header
Include machine/_types.h or sys/_types.h where applicable

Remove a few warnings. Those were not apparent thanks to a bug in gcc 2.95.

Thanks.

zap remaining rcsid.

Kill old files that are no longer compiled.

Change internals of FILE: reuse the unget buffer field to access an
extended attribute data structure (pimpl idiom). Idea taken from citrus.
Much discussion with deraadt@, otto@, millert@...

This is the least disruptive way to extend FILE, since its size can't really
change without this being a flag day. So the size doesn't change.

Actual additions to the structure will come in separate steps, since this
change is nasty enough on its own.

Tests by otto@ and others, careful reading of code by otto@ and millert@.

This is definitely a major bump, and has been checked to not impact a
full ports build.

deregister + ansify, no change in object code. ok deraadt@ millert@

Sync with share/misc/license.template and add missing DARPA credit
where applicable.

Use an ISC-tyle license for all my code; it is simpler and more permissive.

Make sure we free the buffer in all error cases. Do the final
realloc(3) to the size of the string, not the size of the buffer
allocated for the string (which is a noop). mycroft@netbsd.org

realloc repair

Remove the advertising clause in my old license, it impedes free use
of the code as a large number of similar clauses makes it impossible
to write an ad for a product using the code...

Cast pointer in assignment

Based on some FreeBSD changes:
For *s*printf, set f._file to -1 like the comments in stdio.h say.
Use '\0', not 0, where appropriate.
Don't error out on size of '0' for v?snprintf().

Implement asprintf(3) and vasprintf(3) functions similar to the
ones in the glibc. Some man pages changes from FreeBSD
(asprintf.c/vasprintf.c are not based on GNU or FreeBSD code).
