Add debug assertion in libdtoa to catch attempts to use floating point output formats from within an interrupt handler. That will cause assertions or crashes downstream because __dtoa will attempt to allocate memory.

Remove minnsh configurations and support logic: up_getc() and lowinstream.
...
This was an interesting exercise to see just how small you could get NuttX, but otherwise it was not useful: (1) the NSH code violated the OS interface layer by callup up_getc and up_putc directly, and (2) while waiting for character input, NSH would call up_getc() which would hog all of the CPU. NOt a reasonably solution other than as a proof of concept.

Introduce support for Atmel toolchain in-flash strings
...
Atmel toolchain AVR compiler provides a transparent in-flash object support using __flash and __memx symbols. The former indicates to compiler that this is a flash-based object. The later used with pointer indicates that the referenced object may reside either in flash or in RAM. The compiler automatically makes 32-bit pointer with flag indicating whether referenced object is in flash or RAM and generates code to access either in run-time. Thus, any function that accepts __memx object can transparently work with RAM and flash objects.
For platforms with a Harvard architecture and a very small RAM like AVR this allows to move all constant strings used in trace messages to flash in the instruction address space, releasing resources for other things.
This change introduces IOBJ and IPTR type qualifiers. The 'I' indicates that the object may like in instruction space on a Harvard architecture machine.
For platforms that do not have __flash and __memx or similar symbols IOBJ and IPTR are empty, making the types equivalent to, for example, 'const char' and 'const char*'. For Atmel compiler these will become 'const __flash char' and 'const __memx char*'. All printf() functions and syslog() functions are changed so that the qualifier is used with the format parameter.

avsprintf(): Fix a bug in usage of va_list on x86. On x86, va_list is a pointer to a single copy on the stack. avsprintf() calls lib_vsprintf() twice and so traverses the va_list twice using va_start. va_start modifies that single copy on the stack so that the second call to lib_vsprintf() fails. This appears to be an issue with x86 only so far
