archive_{read,write}_open_filename():
* Update Makefile to build the files using the new name.
* Update docs to document the new names, mentioning the
old ones as "deprecated synonyms."
* The old filenames will be reconnected to the build soon;
I'll soon recyce those files for a slightly different purpose.
internal format-specific functions return the same as the public
function, so that the public API layer doesn't have to guess the
correct return value. This addresses an obscure problem that occurs
when someone tries to write more data than the size of the entry (as
indicated in the entry header). In this case, the return value from
archive_write_data() was incorrect, reflecting the requested write
rather than the amount actually written.

- make document title match filename;
- remove hard sentence breaks, whitespace at EOL, and double whitespace;
- sort SEE ALSO xrefs, adding missing section numbers;
- fix a misspelled macro name.
* Use public API, don't access struct archive directly. (People should be able to copy these into their applications as a template for custom I/O callbacks.)
* Set "skip" only for regular files. ("skip" allows the low-level library to catch attempts to add an archive to itself or extract over itself.)
* Simplify the write_open functions by just calling stat() at the beginning. Somehow, these functions had acquired some complex logic that tried to avoid the stat() call but never succeeded.

file. This doesn't happen in normal use, because the file I/O and
decompression layers only pass through smaller blocks. It can happen
with custom read functions that block I/O in larger blocks.
* Actually use the HAVE_<header>_H macros to conditionally include
system headers. They've been defined for a long time, but only
used in a few places. Now they're used pretty consistently
throughout.
* Fill in a lot of missing casts for conversions from void*.
Although Standard C doesn't require this, some people have been
trying to use C++ compilers with this code, and they do require it.
Bit-for-bit, the compiled object files are identical, except for
one assert() whose line number changed, so I'm pretty confident I
didn't break anything. ;-)
h_errno is not an extern int, just a macro providing an integer lvalue.

Remove the const qualifier from ap argument for __v2printf, that induced
that breakage, and seems to be the real reason for bad code. ap is modified
inside the __v2printf body by va_arg macro.

i386 with default optimization level (-O2), va_list pointer ap in the

shift and garbage instead last argument in printf-family when xprintf is

Issue __sflush() before possible setting O_APPEND mode or ftruncate(),

Use simplified _sseek() to the start, if no O_APPEND is set, instead
of _fseeko() (_sseek() to the end, if O_APPEND, occurse later, as for
file != NULL).
Don't check seek error return, as original fopen() and freopen() never
does.

restore it directly and skip chmod() during the post-extract fixup.
In particular, bsdtar -xm now completely skips the post-extract fixup
for directories, which produces a noticable speedup in that case.
With the first part of my previous Summer of Code work, we get:
-made libalias modular:
-support for 'particular' protocols (like ftp/irc/etcetc) is no more
hardcoded inside libalias, but it's available through external
modules loadable at runtime
-modules are available both in kernel (/boot/kernel/alias_*.ko) and
user land (/lib/libalias_*)
-protocols/applications modularized are: cuseeme, ftp, irc, nbt, pptp,
skinny and smedia
-added logging support for kernel side
-cleanup
After a buildworld, do a 'mergemaster -i' to install the file libalias.conf
in /etc or manually copy it.
During startup (and after every HUP signal) user land applications running
the new libalias will try to read a file in /etc called libalias.conf:
that file contains the list of modules to load.
User land applications affected by this commit are ppp and natd:
if libalias.conf is present in /etc you won't notice any difference.
The only kernel land bit affected by this commit is ng_nat:
if you are using ng_nat, and it doesn't correctly handle
ftp/irc/etcetc sessions anymore, remember to kldload
the correspondent module (i.e. kldload alias_ftp).
General information and details about the inner working are available
in the libalias man page under the section 'MODULAR ARCHITECTURE
(AND ipfw(4) SUPPORT)'.
NOTA BENE: this commit affects _ONLY_ libalias, ipfw in-kernel nat
support will be part of the next libalias-related commit.

we can find another way to issue an #error, but using a preprocessed
