577905f1e4 Revert duplicate patch.
I don't know why patch decided to apply this even though it was already in
the tree.  I thought the other hunks failed because they were totally
unrelated leakage from Bernhard's tree (which they are; was the a reason
for bundling them in with this fix?  Do they have something to do with
the GCC 2.95 fix?  I suspect they prevent me from backporting this
patch to 1.2.2 because the header consolidation into libbb.h hadn't
been done yet, and no I'm not fixing it up: if that's the case then
this patch won't be in 1.2.2 due to extraneous changes bundled with it that
prevent a clean backport without rolling a new patch).

b988462d3e Ok, features.h already defines _OPEN_SOURCE (and complains if it's already
defined), yet it's not doing it for scripts/individual for some reason.
(I hate fighting with header files.)

e3781b7312 Add shared subtree support, suggested by Vladimir Dronnikov. Also break out a
few new (unfinished) config options, which I intend to make hidden (but
enabled) when CONFIG_NITPICK is disabled.  Getting the .config infrastructure
to do that is non-obvious, it seems...

148734df99 We came up with our own names for ATTRIBUTE_*, so why check if they're already
#defined?  Also remove a check for a gcc version older than RH9 (if non-linux
needs that #define they can put it in their section.)

22d26fc6ae Patch from Yann Morin to put BLKGETSIZE64 in platform.h had rather a lot of
fallout due to the #include <sys/mount.h>.  Removed that #include from various
applets and fixed up those that were unhappy when that #include was made
because they'd block copied stuff out of it.  (Sigh.)

15d20a03d6 Remove _() and N_() from platform.h. #define them as NOP macros in the two
files still using them.  I didn't remove them from e2fsck.c to avoid stomping
pending cleanup patches from Garrett, and I didn't bother to remove them from
fdisk.c because that entire file needs to be rewritten from scratch.

as the old optimization did (actually does slightly better under gcc 4.0), and

5cf7c2df66 Patch from Devin Bayer to split up hash_fd.c into md5.c and sha1.c. (I tweaked
md5_sha1_sum.c to convert some #ifdef CONFIG to if(ENABLE).)

7bfa88f315 New USE() macros
For each CONFIG_SYMBOL, include/bb_config.h now has both ENABLE_SYMBOL
and USE_SYMBOL(x).  ENABLE_SYMBOL is still always defined (1 or 0) so that
if(ENABLE) should optimize out when it's zero.  The USE_SYMBOL(X) will only
splice in X if the symbol is defined, otherwise it'll be empty.

Thus we can convert this:

#ifdef CONFIG_ARGS
    opt = bb_getopt_ulflags(argc, argv, "ab:c"
#ifdef CONFIG_THINGY
        "d:"
#endif
        , &bvalue
#ifdef CONFIG_THINGY
        , &thingy
#endif
    );
#endif

into this:
    if (ENABLE_ARGS) {
        opt = bb_getopt_ulflags(argc, argv, "ab:c" USE_THINGY("d:"), &bvalue
                USE_THINGY(, &thingy));
    }

And it should produce the same code.

Unlike the old versions in include/_usage.h, the new USE_SYMBOL(x) can handle
commas in its arguments (as shown above).  (The _usage.h file is obsolete and
no longer generated.)

Nobody should need to include config.h directly anymore, bb_config.h should
define all the configuration stuff we need.  Someday, the CONFIG_SYMBOL
versions should go away in favor of ENABLE_SYMBOL and USE_SYMBOL().

Thanks to vodz for the new version of bb_mkdep.c that works with function
macros.
