0bd58a5613 esp8266/machine_pin: Move pin_intr_handler to iRAM, de-support hard IRQ.
GPIO interrupts can occur when the flash ROM cache is in use and so the
GPIO interrupt handler must be in iRAM.  This commit moves the handler to
iRAM, and also moves mp_sched_schedule to iRAM which is called by
pin_intr_handler.

As part of this fix the Pin class can no longer support hard=True in the
Pin.irq() method, because the VM and runtime are too big to put in iRAM.

Fixes #5714.

8d0421c3cf esp8266: Put mp_keyboard_interrupt in IRAM.
It was originally in IRAM due to the linker script specification, but
since the function moved from lib/utils/interrupt_char.c to py/scheduler.c
it needs to be put back in IRAM.

b47e155bd0 py/persistentcode: Add ability to relocate loaded native code.
Implements text, rodata and bss generalised relocations, as well as generic
qstr-object linking.  This allows importing dynamic native modules on all
supported architectures in a unified way.

cea9209e0f esp8266/moduos: Add optional support for VfsLfs1 and VfsLfs2.
With this commit an esp8266-based board can now be built with littlefs
support via, eg "make MICROPY_VFS_LFS2=1".

d2384efa80 py: Automatically provide weak links from "foo" to "ufoo" module name.
This commit implements automatic module weak links for all built-in
modules, by searching for "ufoo" in the built-in module list if "foo"
cannot be found.  This means that all modules named "ufoo" are always
available as "foo".  Also, a port can no longer add any other weak links,
which makes strict the definition of a weak link.

It saves some code size (about 100-200 bytes) on ports that previously had
lots of weak links.

Some changes from the previous behaviour:
- It doesn't intern the non-u module names (eg "foo" is not interned),
  which saves code size, but will mean that "import foo" creates a new qstr
  (namely "foo") in RAM (unless the importing module is frozen).
- help('modules') no longer lists non-u module names, only the u-variants;
  this reduces duplication in the help listing.

Weak links are effectively the same as having a set of symbolic links on
the filesystem that is searched last.  So an "import foo" will search
built-in modules first, then all paths in sys.path, then weak links last,
importing "ufoo" if it exists.  Thus a file called "foo.py" somewhere in
sys.path will still have precedence over the weak link of "foo" to "ufoo".

See issues: #1740, #4449, #5229, #5241.

53a9b45da1 esp8266: Add per-board configs, following other ports.
The specific board can be selected with the BOARD makefile variable.  This
defaults (if not specified) to BOARD=GENERIC, which is the original default
firmware build.  For the 512k target use BOARD=GENERIC_512K.

bc4f8b438b extmod/moduwebsocket: Refactor websocket to uwebsocket.
As mentioned in #4450, `websocket` was experimental with a single intended
user, `webrepl`. Therefore, we'll make this change without a weak
link `websocket` -> `uwebsocket`.

da2d2b6d88 py/mpconfig.h: Introduce MICROPY_DEBUG_PRINTER for debugging output.
This patch in effect renames MICROPY_DEBUG_PRINTER_DEST to
MICROPY_DEBUG_PRINTER, moving its default definition from
lib/utils/printf.c to py/mpconfig.h to make it official and documented, and
makes this macro a pointer rather than the actual mp_print_t struct.  This
is done to get consistency with MICROPY_ERROR_PRINTER, and provide this
macro for use outside just lib/utils/printf.c.

Ports are updated to use the new macro name.

afd0701bf7 esp8266: Change UART(0) to attach to REPL via uos.dupterm interface.
This patch makes it so that UART(0) can by dynamically attached to and
detached from the REPL by using the uos.dupterm function.  Since WebREPL
uses dupterm slot 0 the UART uses dupterm slot 1 (a slot which is newly
introduced by this patch).  UART(0) must now be attached manually in
boot.py (or otherwise) and inisetup.py is changed to provide code to do
this.  For example, to attach use:

    import uos, machine
    uart = machine.UART(0, 115200)
    uos.dupterm(uart, 1)

and to detach use:

    uos.dupterm(None, 1)

When attached, all incoming chars on UART(0) go straight to stdin so
uart.read() will always return None.  Use sys.stdin.read() if it's needed
to read characters from the UART(0) while it's also used for the REPL (or
detach, read, then reattach).  When detached the UART(0) can be used for
other purposes.

If there are no objects in any of the dupterm slots when the REPL is
started (on hard or soft reset) then UART(0) is automatically attached.
Without this, the only way to recover a board without a REPL would be to
completely erase and reflash (which would install the default boot.py which
attaches the REPL).
