Collect a new histogram (Platform.CpuUsage.Percent), collecting the
average cpu usage in percent of the total cpu usage possible (across all
cpus).
This measurement is collected every minute.

Allow adb to build using gcc by explicitly using global scope for the
type for pollfd. An alternative would be to rename the pollfd field to
different, but I did not have a better name in mind.

if ro.logd.timestamp or persist.logd.timestamp are set to the value
monotonic then liblog writer, liblog printing and logd all switch to
recording/printing monotonic time rather than realtime. If reinit
detects a change for presist.logd.timestamp, correct the older entry
timestamps in place.
ToDo: A corner case condition where new log entries in monotonic time
occur before logd reinit detects persist.logd.timestamp, there
will be a few out-of-order entries, but with accurate
timestamps. This problem does not happen for ro.logd.timestamp
as it is set before logd starts.
NB: This offers a nano second time accuracy on all log entries
that may be more suitable for merging with other system
activities, such as systrace, that also use monotonic time. This
feature is for debugging.

$USER and $LOGNAME along with $HOME were just plain wrong (leading to a
misleading interactive prompt), and it probably makes sense to reset the
variables that su would reset.

Before:

Couldn't parse partition size '3321fa800'.

Couldn't parse partition size '2bc00000'.
Groan. So much variation between bootloaders. I wish we had a reference
bootloader like ChromeOS does.
I've also removed a harmless warning:
couldn't parse max-download-size ''

Our Windows code has several different ways it checks whether an FD is
a console or not, some of which aren't exactly correct as they may
treat character devices (e.g. NUL) as consoles.
This CL disallows using the builtin isatty() function and provides
unix_isatty() instead which correctly checks these corner cases.

It's probably not the only device whose bootloader is similarly broken.
NVIDIA did a sufficiently good job with Nexus 9 that it's almost a bad
idea for me to do most of my development there...

Previously we've set these from /system/etc/mkshrc, which caused a behavioral
difference between interactive and non-interactive shells.

Building without ramdisk requires a way to specify board specific
directoryies and symlinks in the root directory at build time.
