An ELF file with no program headers is valid, and binutils leaves e_phentsize
zero in that case. Fix the corruption check to cope.
Also, since notes are in both the program and section headers (and I'm not
aware of the possibility of having no sections but still having notes ---
where would they be?), look for them in the section headers instead.
Also extend the parsing of the .android.note.ident ELF note to include the
NDK version information if present. (This won't be present for platform
binaries, but will be present for NDK-built binaries such as app libraries.)

I knew that just showing the process name was a divergence from
traditional Android behavior, but I was curious to see whether anyone
cared. Bug reports show that they do. I've not made this conditional on
CFG_TOYBOX_ON_ANDROID on the assumption that this is more useful for
everyone else too. (Why are you asking for per-thread information if
you don't actually want to be able to identify individual threads?)
Why not _just_ show the thread name? Because on Android at least, every
process has lots of identically-named threads; everyone has GC threads,
everyone has JIT threads, and so knowing _just_ the thread name is
rarely useful.
Why show thread name first? Because the kernel limits thread names to 15
bytes plus a NUL, so any left-over space should go to the process name,
so that should come last.
Why call the thread name THREAD? Because "CMD" isn't obviously "thread
name" to folks who don't know how this is implemented behind the scenes.
This change also removes an incorrect "usage:" comment. None of the
other commands in this file duplicated their "usage:" lines, and this
copy wasn't even close to being correct.

commandline tool fails to sort by the 3rd,4th,etc column. For example: when you exec
$ sort -t',' -k 3n
on a file which cotains:
1,2,3,4
2,3,4,1
4,1,2,3
3,4,1,2
you got:
4,1,2,3
1,2,3,4
2,3,4,1
3,4,1,2
but the expected output should be:
3,4,1,2
4,1,2,3
1,2,3,4
2,3,4,1
The bug is due to the dependency of "isspace(str[end])" at line 113.
When searching for the non-space key_separator, the search stopped just at the position of first key_separator it met.
The bug can be easily fixed by adding "end++" when the search have found one separator and exit the for loop.

line aren't filtered out. Audited all the callers and removed redundant
calls, adjusted call sequence, etc. (And let rm _not_ do this, because posix.)

This fixes an indirect function call through a pointer of an
incompatible type.

reliably be distinguished by checking length, because %H amd %m and such
can match different numbers of digits.)
|

T to be a space instead (because the posix says so, no idea why), initialize
default values reliably including zeroing daylight savings time field (which is
handled inconsistently by libc and just screws stuff up).

It's causing confusion, and it's not obvious that anyone's relying on
it (and even if they are, let's try to find and fix them first).

(no /proc/$PID/cmdline so setting was skipped and previous value retained),
which led to memcpy() with an overlapping source/dest range (annoying asan).
Fix: move temp variable and assignment outside the if() statement so we assign
zero if we can''t read the file.

Say "toybox" before version string. Tweak sed to preserve lie-to-autoconf.

POSIX says nothing, but traditional ps lets you say "ps 123" in addition
to "ps -p 123". (You can mix and match too: "ps -p 123,124 666 667" works
fine.)

Android uses NAME rather than CMD by default, but that's not what we
want with -T. Noticed because it broke systrace's reporting of thread
names (see https://developer.android.com/studio/profile/systrace.html).

On a toybox system, most of your bin directory is symbolic links.

then reading from stdin if it detected a file). Fixed it so "-" always
means stdin and you have to say ./- to look at a local "-".
Did some whitespace tweaks while I was there...

Or more accurately, s@[[:space:]@]@replace@ which can't treat the @ in
[] as a delimiter but has to know about nested [[]] to make that decision.

(Two spaces padding between columns, and -k is hardwired on.)

(We should use xprintf and similar to flush and check if stdout went away
once per line. No point flushing partway through a line, so in ls only use it
on things outputting a newline char.)

-h should apply to -s too. (Previously it only applied to the "total"
line in -s output.)

instead of a struct. This means it can return "12345" even if that user/group
doesn't exist in /etc/passwd and similar.
All the users were immediately dereferencing it to get pw_uid or gr_gid
anyway, so just return it directly and adjust the users. This fixes
things like "chown 12345:23456 filename".

add xopenro() that takes one argument and understands "-" means stdin,
and switch over lots of users.

The IANA tzcode implementation of mktime (used on Android and BSDs) sets
errno in some cases where it doesn't return -1 to indicate failure, so the
existing test always failed on those systems.
I don't think glibc ever sets errno (which is fine by ISO C, but not POSIX).
Other uses of mktime in toybox are already fine. This one would have been
caught by the existing tests if I was running them on the device :-(

This is enough for everything on Android and everything except Java

They're really just arbitrary byte sequences of arbitrary length.
Sure, a 20-byte sequence is _probably_ a SHA-1, but there's no way
to know, so let's stop pretending...
