stop lying about [[ test support
probably because it was not properly ifdefed around, and was enabled
even when bash compat is off.
I just tested it - it works:
$ [ *.diff = z.diff ]; echo $?
0
$ [[ *.diff = z.diff ]]; echo $?
1
Of course, not all numerous bash tricks of [[ ]] are implemented...

Allow FAST_FUNC to be overridden at build time
Busybox uses FAST_FUNC macro to tweak with IA-32 calling conventions in
order to make the function call slightly smaller or slightly faster.
However, when I experiment with GCC's LTO (Link Time Optimization), I
discovered that FAST_FUNC could hinder LTO's optimization so that the
resulting executable become a few bytes larger (than what is compiled
without FAST_FUNC).
This change allows to specify e.g.
CONFIG_EXTRA_CFLAGS="-DFAST_FUNC= -flto"
and compile with LTO without a source code hack.

LZMA SDK from lzma1604.7z has the following in the corresponding places:
... = dic[dicPos - rep0 + (dicPos < rep0 ? dicBufSize : 0)]
Clearly, not loop here.
Technically, "while" here works: if condition is false (because pos
underflowed), it iterates once, adds header.dict_size (a.k.a. dicBufSize),
this makes pos positive but smaller than header.dict_size, and loop exits.
Now we'll just check for negative result of subtraction, which is less code:

This happens because SEAMLESS_MAGIC != 0 and compiler is unable

Fix this by disabling SEAMLESS_MAGIC option flag (setting its value

This would makes all ash options indented inside "ash" in menuconfig.
It appears that menuconfig has a limit at tracking multiple dependency
lines like this (it looks like a "diamond problem" but I'm not sure if
it is):
---ASH <----------
/ \ ASH_OPTIMIZE_FOR_SIZE
!NOMMU <-*----SH_IS_ASH <----[OR] <--ASH_INTERNAL_GLOB
\ / ASH_RANDOM_SUPPORT
---BASH_IS_ASH <-- [...]
The kconfig-language document [1] states that:
> If a menu entry somehow depends on the previous entry, it can be
> made a submenu of it. First, the previous (parent) symbol must be
> part of the dependency list and then one of these two conditions

[BusyBox ash used to satisfy this, but no longer does]
> - the child entry must only be visible, if the parent is visible
[BusyBox ash configs actually satisfy this, but because of
"diamond" above this might not be easily detected]
So I found out a direct workaround: by making ash options explicitly
depend on !NOMMU, we can tell menuconfig that rule 2 above is satisfied
without any more tracking.

!NOMMU <-*-----ASH <-------- \

modutils: remove special handling of uClibc
Commit
3a45b87ac36f (modutils: support finit_module syscall) introduced
macro finit_module. But it is not defined for uClibc.
The compilation for busybox fails for MIPS with:
With uClibc, we get following build errors:
modutils/lib.a(modutils.o): In function `bb_init_module':
modutils.c:(.text.bb_init_module+0x94): undefined reference to `finit_module'
modutils.c:(.text.bb_init_module+0xa0): undefined reference to `finit_module'
We can just use syscall() without any need for the
uClibc wrappers.
Newer versions of uClibc-ng (>1.0.20) will remove the
module syscall wrappers.

Fix dependency for IFUPDOWN_UDHCPC_CMD_OPTIONS
Commit
a8c696bf09d8151323f6e99348c4bc8989f829c8 makes ifup and ifdown
individually selectable, but forgets to update the dependency to
IFUPDOWN_UDHCPC_CMD_OPTIONS, so it is not selectable anymore.
This patch fixes the dependency by checking for IFUP or IFDOWN, instead
of the obsolete IFUPDOWN.
Also, it drops dependency on UDHCPC: udhcpc on the target system
does not have to come from the _same_ binary.

libiproute: handle table ids larger than 255
Linux kernel, starting from 2.6.19 allows ip table ids to have 32-bit values.
In order to preserve compatibility, the old 8-bit field: rtm_table is still
in use when table id is lower than 256.
Add support for the 32-bit table id (RTA_TABLE attribute) in:
- ip route print
- ip route modify
- ip rule print
- ip rule modify
Add printing of table ids to ip route.
Changes are compatible with the mainline iproute2 utilities.
These changes are required for compatibility with ConnMan, which by default
uses table ids greater than 255.
