Android O removes name length limit for system properties.
Use __system_property_read_callback instead of deprecated
__system_property_read in getprop and remove check for
property name length in setprop.
Test: adb shell setprop debug.test.very.very.long.property.name valueforpropertywithlongname
Test: adb shell getprop | grep debug.test.very.very.long.property.name

Recognize full range of linux serial speeds (only error cfsetspeed returns
is invalid speed value).
|

Our device bringup folks wanted a simple serial console, both on the
host and on the device. This is certainly enough to replace what I've
been using personally on the host.
I'd never heard of "microcom" until I asked the internets what busybox
users use, so I don't care what we call this or what the options are
called. (But would like to decide before it gets ossified in a million
factory test scripts and the like!)
The tool that this replaces for me defaulted to /dev/ttyUSB0, but since
I don't know whether that default would be useful for most other people
too, I left that out. Command-line history will solve my transition
problem.

for a reason and I need to completely rewrite it.

(The switch to 64 bits screwed up varargs: everything used to be promoted to 32
bits, but now it's 32 bits or 64 bits depending on type declarations, so you
need the type declarations. Because promoting "char" arguments to 32 bits back
when a megabyte was a lot of memory was ok, but promoting everything to 64 bits
now that you can get 2 gigabytes of ram in a phone is unacceptable.)

make xsocket()'s returned fd CLOEXEC.

shouldn't segfault falling off the end of the list trying to report a
nonexistent error condition.

and although it was partially restored by https://lwn.net/Articles/699704/
that didn't include this list.

POSIX does have a name for the struct timespec in struct stat.
|
|
sizeof(int) != sizeof(size_t) for LP64, leading to hilarity^Wcrashes.
|

The "lsm" portability stuff could abstract this away, but Android doesn't
need it, and getprop is meaningless on non-Android. (And if you're just
building with the NDK, on recent enough versions of Android you won't be
able to read most of the system properties anyway because access to them is
increasingly restricted by selinux.)

Removes the dependency on libcutils for everything except ps.

A "globally unique 32 bit number" is a concept the Linux world has outgrown.

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.

Kernel can handle 64k maximum segment size.

So use $SED to indicate the sed to use, and set it to 'gsed' if available.

(This made ls -l not work when LS_COLOR was off.)

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.)
|

screwed up "tar c" to stdout.

This fixes an indirect function call through a pointer of an
incompatible type.
See http://clang.llvm.org/docs/ControlFlowIntegrity.html for more
details.

Annoyingly, this means writing a new dmesg implementation that uses /dev/kmsg
rather than the klogctl system call. Worse, pre-3.5 kernels don't support
that, so we need to keep the old implementation around as long as we still
care about those kernels.
Since I'm here, add the fancy colors from modern dmesg and the -C flag.
Tested on Nexus 9's 3.10 kernel, an Ubuntu 3.13 kernel, and the
Nexus One's 2.6.35 kernel.

Also improve error reporting.
