apps/examples/pty_test:  Use of POLL must be optional. There are still a few character drivers that do not support it.

When Priority Inheritance is enabled, the format of /proc/<PID>/status changes to show both the current priority and the thread’s base priority.  This messes up the format of cmd_ps.

The attached patch fixes cmd_ps to ignore the base priority.

ESP8266 Kconfig:  Select ARCH_HAVE_NET when NETUTILS_ESP8266 is selected.  This allows, among other things, support for network debug output.

Add apps/include to include path in top-level Make.defs file.  Remove multiple definitions of INCDIR opt.

Recent enhancements to cmd_ps trips a floating point exception if LIBC_FLOATINGPOINT is not defined (at least on Cortex M4 w/ hardfloat).  I’m using a buildroot gcc configured to support Cortex-M4F and the hard float ABI, target files are compiles with: -mcpu=cortex-m4 -mthumb -mfpu=fpv4-sp-d16 -mfloat-abi=hard.  I’m not sure the best way to address this, but the attached patch file is the first that comes to mind.  Note, I added the float qualifier ‘F’ after a few constants to prevent the compiler from promoting the multiplication and division to double (expensive on M4F) then demoting to single float for the store.  (sorry, it’s one of my many pet peeves ;)

The NTP client will now optionally use pool.ntp.org as the NTP server; and reset the retry count upon success -- more robust.
