In certain systems, where -std=c11 is used, certain posix extensions
are disabled unless specifically enabled. On these systems, this
could cause usleep() and/or nanosleep() to fail with an implicit
declaration warning. This patch ensures that at least POSIX 200809 is
used, if otherwise undefined.
This should fix Issue #513.

usleep() has been deprecated, and can cause compile problems on never
glibc versions (debian jesse). We now use nanosleep() on linux
systems to implement delays.

These changes add the ability to intialize a speaker instance to use a
PWM pin instead of a standard GPIO pin in order to emit sounds.
The current GPIO functionality is fairly constrained by the
implementation -- it only permits playing cerain hardcoded "notes".
The PWM support allows one to emit specific frequencies (currently
between 50-32Khz) using a PWM pin. Of course, you may still be
constrained by the limits of your PWM hardware in the end.
There are a few new functions provided to support this PWM mode. To
use the PWM mode of speaker, use the speaker_init_pwm() initialization
routine instead of speaker_init() (for C). For C++ and the SWIG
languages, pass "true" as the second argument to the constructor to
enable PWM mode. The default is "false", to match current default
behavior (GPIO).
Functions that are not related to a given mode (GPIO vs. PWM) will do
nothing if not usable in that mode.

uartat is the underlying UART driver, specifically for use with
AT-style command driven devices like modems.
The le910 support is provided in the form of examples that make use
of the uartat driver to interact with the device.

Previously, the C++ and C versions of this driver were separate. Now
the C++ implementation wraps the C implementation.
In addition, the C++ init() function has been deprecated. It
currently does nothing, and examples have been modified to remove it's
calls. This function will be removed in a separate release.
The examples have been further modified to update all detected devices
and print their respective temperatures, instead of only reporting the
on the first device detected.

Handle failure in ISR routine - attempt to read status and
FIFO registers and continue sampleing (vs exiting and turning
off continuous sampling).

- Fixed the Zephyr kernel version checks to check for 0.1.6 rather
than 1.6.0.
- fixed the k_timer implementation to actually work. None of these
were being called correctly.
- due to the fact that the k_timer API only has a 1ms resolution,
re-implement upm_delay_us() (on 0.1.6 version of zephyr) as a busy
loop using a upm_clock_t.

If directories are specified with -DMODULE_LIST=blah, it's
possible to skip adding the utilities directory which is needed
by *most* sensor library targets in UPM. Added a check for this
when using -DMODULE_LIST.

Fixed a problem where the C/CXX compile flags were getting
overwritten. Fixed warnings in a few sensor drivers.
