all: Unify header guard usage. The code conventions suggest using header guards, but do not define how those should look like and instead point to existing files. However, not all existing files follow the same scheme, sometimes omitting header guards altogether, sometimes using non-standard names, making it easy to accidentally pick a "wrong" example. This commit ensures that all header files of the MicroPython project (that were not simply copied from somewhere else) follow the same pattern, that was already present in the majority of files, especially in the py folder. The rules are as follows. Naming convention: * start with the words MICROPY_INCLUDED * contain the full path to the file * replace special characters with _ In addition, there are no empty lines before #ifndef, between #ifndef and one empty line before #endif. #endif is followed by a comment containing the name of the guard macro. py/grammar.h cannot use header guards by design, since it has to be included multiple times in a single C file. Several other files also do not need header guards as they are only used internally and guaranteed to be included only once: * MICROPY_MPHALPORT_H * mpconfigboard.h * mpconfigport.h * mpthreadport.h * pin_defs_*.h * qstrdefs*.h

py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros. In order to have more fine-grained control over how builtin functions are constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific, with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW. These names now match the MP_DEFINE_CONST_FUN_OBJ macros.

esp8266: Move pyb.info() function to esp module and remove pyb module. All functionality of the pyb module is available in other modules, like time, machine and os. The only outstanding function, info(), is (temporarily) moved to the esp module and the pyb module is removed.

esp8266: Convert mp_hal_pin_obj_t from pin ptr to simple integer. Most pin I/O can be done just knowing the pin number as a simple integer, and it's more efficient this way (code size, speed) because it doesn't require a memory lookup to get the pin id from the pin object. If the full pin object is needed then it can be easily looked up in the pin table.

esp8266/machine_pwm: Enable real open drain output on pin driven by PWM. The PWM module now detects if the pin is open drain and if so switches it to hardware open drain before starting the PWM. The code that was explicitly turning off the open drain output during PWM is also removed. Together these changes allow driving external transistor high-current switches with PWM.

esp8266: Rename "machine" module implementation to use contemporary naming. Previously they used historical "pyb" affix causing confusion and inconsistency (there's no "pyb" module in modern ports; but people took esp8266 port as an example, and "pyb" naming kept proliferating, while other people complained that source structure is not clear).

all: Rename absolute time-based functions to include "epoch". For time-based functions that work with absolute time there is the need for an Epoch, to set the zero-point at which the absolute time starts counting. Such functions include time.time() and filesystem stat return values. And different ports may use a different Epoch. To make it clearer what functions use the Epoch (whatever it may be), and make the ports more consistent with their use of the Epoch, this commit renames all Epoch related functions to include the word "epoch" in their name (and remove references to "2000"). Along with this rename, the following things have changed: - mp_hal_time_ns() is now specified to return the number of nanoseconds since the Epoch, rather than since 1970 (but since this is an internal function it doesn't change anything for the user). - littlefs timestamps on the esp8266 have been fixed (they were previously off by 30 years in nanoseconds). Otherwise, there is no functional change made by this commit. Signed-off-by: Damien George <damien@micropython.org>
