17ba6ef5fa cc3200: Fix thread mutex's so threading works with interrupts. 
Running Python code on a hard interrupt is incompatible with having a GIL,
because most of the time the GIL will be held by the user thread when the
interrupt arrives.  Hard interrupts mean that we should process them right
away and hence can't wait until the GIL is released.

The problem with the current code is that a hard interrupt will try to
exit/enter the GIL while it is still held by the user thread, hence leading
to a deadlock.

This patch works around such a problem by just making GIL exit/enter a
no-op when in an interrupt context, or when interrupts are disabled.

See issue #2406.

204222653e esp8266/main: Mark nlr_jump_fail() as MP_FASTCODE. 
It's probably not strictly needed so far, but serves as an example of
MP_FASTCODE use and may be helpful in the future.

9514d847fe esp8266: Add MP_FASTCODE modifier to put a function to iRAM.

20d0271863 esp8266/esp_init_data: Auto-initialize system params with vendor SDK 2.0.0. 
SDK 2.0.0 goes into boot loop if a firmware is programmed over erased flash,
causing problems with user experience. This change implements behavior
similar to older SDKs': if clean flash is detected, default system
parameters are used.

b4cc68e4a4 stmhal/led: Refactor LED to use mp_hal_pin_output() init function. 
As part of this patch the MICROPY_HW_LED_OTYPE setting is removed because
it is now unused (all boards anyway had this as OUTPUT_PP).

a97284423e extmod/utime_mphal: Factor out implementations in terms of mp_hal_* for reuse. 
As long as a port implement mp_hal_sleep_ms(), mp_hal_ticks_ms(), etc.
functions, it can just use standard implementations of utime.sleel_ms(),
utime.ticks_ms(), etc. Python-level functions.

824f5c5a32 py/vstr: Combine vstr_new_size with vstr_new since they are rarely used. 
Now there is just one function to allocate a new vstr, namely vstr_new
(in addition to vstr_init etc).  The caller of this function should know
what initial size to allocate for the buffer, or at least have some policy
or config option, instead of leaving it to a default (as it was before).

b6a544b917 zephyr: Implement the help() function.

the user to run it. It is very disconcerting to find that the
function does not exist...

4021b1e1b8 lib/utils/pyexec: Don't treat SystemExit as "forced exit". 
"Forced exit" is treated as soft-reboot (Ctrl+D). But expected effect of
calling sys.exit() is termination of the current script, not any further
and more serious actions like mentioned soft reboot.
