fixes to read_support_compression_program. In particular, failure of
the external program is detected a lot earlier, which gives much more
reasonable error handling.
corrections to the Windows support to reconcile differences
between Visual Studio and Cygwin. Includes parts of
revisions 757, 774, 787, 815, 817, 819, 820, 844, and 886.
Of particular note, r886 overhauled the UTF-8/Unicode conversions to
work correctly regardless of whether the local system uses 16-bit
or 32-bit wchar_t. (I assume that systems with 16-bit wchar_t
use UTF-16 and those with 32-bit wchar_t use UCS-4.) This revision
also added a preference for wcrtomb() (which is thread-safe) on
platforms that support it.
r751: Change __archive_strncat() to use a void * source, which reduces
the amount of casting needed to use this with "char", "signed char"
and "unsigned char".
r752: Use additions instead of multiplications when growing buffer;
faster and less chance of overflow.
support for virtual core files (aka minidumps). physical core
files are not supported.
The implementation is cross-tool ready and can be used in a non-
powerpc hosted debugger to analyze PowerPC core files. It also
accepts core files that still have the dump header, as can be
the case within Juniper where TFTP-based kernel core files are
supported and savecore is not used to "extract" the core file
from some dump device.

because it means getdelim() returns -1 for both error and EOF, and
never returns 0. However, this is what the original GNU implementation
does, and POSIX inherited the bug.

dlfunc() called dlsym() to do the work, and dlsym() determines the dso
that originating the call by the return address. Due to this, dlfunc()
operated as if the caller is always the libc.
To fix this, move the dlfunc() to rtld, where it can call the internal
implementation of dlsym, and still correctly fetch return address.
Provide usual weak stub for the symbol from libc for static binaries.
dlfunc is put to FBSD_1.0 symver namespace in the ld.so export to
override dlfunc@FBSD_1.0 weak symbol, exported by libc.

these functions were moved into the kernel:
- Move the version entries from gen/ to sys/. Since the ABI of the actual
routines did not change, I'm still exporting them as FBSD 1.0 on purpose.
- Add FBSD-private versions for the _ and __sys_ variants.
This does not include the new hash routines since they will cause problems
when reading old hash files.
Since mpool(3) has been changed, provide a compatibility shim for older

While there, remove the PURIFY option. There is a slight difference between
the new behavior and the old -DPURIFY behavior, with the latter initializes
memory with 0xff's. The difference between old and new approach does not
generate observable difference.

Now, getaddrinfo(3) returns two SOCK_STREAMs, IPPROTO_TCP and
IPPROTO_SCTP. It confuses some programs. If getaddrinfo(3) returns
IPPROTO_SCTP when SOCK_STREAM is specified by hints.ai_socktype, at
least Apache doesn't work. So, I made getaddrinfo(3) to return
IPPROTO_SCTP with SOCK_STREAM only when IPPROTO_SCTP is specified
explicitly by hints.ai_protocol.
