[*] Refactor AuCompression APIs
[*] Clean up AuTryConstructs
[+] Internal compression API for compression based interceptors
[+] Root-level input stream arg check for all compression apis (harden)
[*] Clean up AuCompression code
[+] Solar Designer / OpenWall blowfish crypt
[*] BlowCrypt: accept length input parameter
[*] Split locale into 2 source files
[-] Ugly comment from Open.Win32.cpp. TODO: Readd later. Might warn on empty string bc it makes sense given, "." and "/" normalizes to nothing, and memory pre-idc-if-drops are dropped siliently.

This is an implementation of a password hashing method, provided via the
crypt(3) and a reentrant interface. It is fully compatible with
OpenBSD's bcrypt.c for prefix "$2b$", originally by Niels Provos and
David Mazieres. (Please refer to the included crypt(3) man page for
information on minor compatibility issues for other bcrypt prefixes.)
I've placed this code in the public domain, with fallback to a
permissive license. Please see the comment in crypt_blowfish.c for
more information.
You can use the provided routines in your own packages, or link them
into a C library. I've provided hooks for linking into GNU libc, but
it shouldn't be too hard to get this into another C library. Note
that simply adding this code into your libc is probably not enough to
make your system use the new password hashing algorithm. Changes to
passwd(1), PAM modules, or whatever else your system uses will likely
be needed as well. These are not a part of this package, but see
LINKS for a pointer to our tcb suite.
Instructions on using the routines in one of the two common ways are
given below. It is recommended that you test the routines on your
system before you start. Type "make check" or "make check_threads"
(if you have the POSIX threads library), then "make clean".
1. Using the routines in your programs.
The available interfaces are in ow-crypt.h, and this is the file you
should include. You won't need crypt.h. When linking, add all of the
C files and x86.S (you can compile and link it even on a non-x86, it
will produce no code in this case).
2. Building the routines into GNU C library.
For versions 2.13 and 2.14 (and likely other nearby ones), extract the
library sources as usual. Apply the patch for glibc 2.14 provided in
this package. Enter crypt/ and rename crypt.h to gnu-crypt.h within
that directory. Copy the C sources, header, and assembly (x86.S) files
from this package in there as well (but be sure you don't overwrite the
Makefile). Configure, build, and install the library as usual.
For versions 2.2 to 2.3.6 (and likely also for some newer ones),
extract the library sources and maybe its optional add-ons as usual.
Apply the patch for glibc 2.3.6 provided in this package. Enter
crypt/ and rename crypt.h to gnu-crypt.h within that directory. Copy
the C sources, header, and assembly (x86.S) files from this package in
there as well (but be sure you don't overwrite the Makefile).
Configure, build, and install the library as usual.
For versions 2.1 to 2.1.3, extract the library sources and the crypt
and linuxthreads add-ons as usual. Apply the patch for glibc 2.1.3
provided in this package. Enter crypt/sysdeps/unix/, and rename
crypt.h to gnu-crypt.h within that directory. Copy C sources, header,
and assembly (x86.S) files from this package in there as well (but be
sure you don't overwrite the Makefile). Configure, build, and install
the library as usual.
Programs that want to use the provided interfaces will need to include
crypt.h (but not ow-crypt.h directly). By default, prototypes for the
new routines aren't defined (but the extra functionality of crypt(3)
is indeed available). You need to define _OW_SOURCE to obtain the new
routines as well.

* There was a sign extension bug in older revisions of this function. While
* we would have liked to simply fix the bug and move on, we have to provide
* a backwards compatibility feature (essentially the bug) for some systems and
* a safety measure for some others. The latter is needed because for certain
* multiple inputs to the buggy algorithm there exist easily found inputs to
* the correct algorithm that produce the same hash. Thus, we optionally
* deviate from the correct algorithm just enough to avoid such collisions.
* While the bug itself affected the majority of passwords containing
* characters with the 8th bit set (although only a percentage of those in a
* collision-producing way), the anti-collision safety measure affects
* only a subset of passwords containing the '\xff' character (not even all of
* those passwords, just some of them). This character is not found in valid
* UTF-8 sequences and is rarely used in popular 8-bit character encodings.
* Thus, the safety measure is unlikely to cause much annoyance, and is a
* reasonable tradeoff to use when authenticating against existing hashes that
* are not reliably known to have been computed with the correct algorithm.
*
* We use an approach that tries to minimize side-channel leaks of password
* information - that is, we mostly use fixed-cost bitwise operations instead
* of branches or table lookups. (One conditional branch based on password
* length remains. It is not part of the bug aftermath, though, and is
* difficult and possibly unreasonable to avoid given the use of C strings by
* the caller, which results in similar timing leaks anyway.)
*
* For actual implementation, we set an array index in the variable "bug"
* (0 means no bug, 1 means sign extension bug emulation) and a flag in the
* variable "safety" (bit 16 is set when the safety measure is requested).
* Valid combinations of settings are:
*
* Prefix "$2a$": bug = 0, safety = 0x10000
* Prefix "$2b$": bug = 0, safety = 0
* Prefix "$2x$": bug = 1, safety = 0

* not any worse than any other choice we could make.)

// Fuck tons of applications support clicking of links, in the case of TS and others, allowing for RCE.
// In the case of MC and others, they don't even know if the operation blocks until the process closes.
// Assuming non-blocking, the API returns false on failure; but if it's blocking, who knows what that
// means... Nonzero exit code? Not enough resources? No error?
//
// Websites, programs, and scripts wouldn't know how to process "missing protocol handler,"
// "not enough resources," "process crashed before pump," "shell busy." For the most part, we don't
// expect expect the developer to be aware of what happens after a request to open a resource is
// requested. It's a lot of engineering effort for what should be fork, exec("start", ...)
