Move all exception strings to IRAM and out of both PMEM (illegal) and add output of any assert() failinf conditions. The exception handler may be called while the SPI interface is in a bad state. This means no PROGMEM reads are allowed, and all data and functions used must be in system RAM or IRAM. Add a new helper macro, ets_printf_P(), which places a constant string in IRAM and copies it to the stack before calling the real ets_printf(). This makes the code simpler to read as no unwieldy combinations of ets_putc/ets_printf/... are required to output anything. The old handler also mistakenly used PSTR() strings in some places, so fix those with this patch as well. Gives back ~180 bytes of heap to every sketch built as the exception handler is always included an application.
