all: Add py/mphal.h and use it in all ports. py/mphal.h contains declarations for generic mp_hal_XXX functions, such as stdio and delay/ticks, which ports should provide definitions for. A port will also provide mphalport.h with further HAL declarations.

all: Use the name MicroPython consistently in comments There were several different spellings of MicroPython present in comments, when there should be only one.

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

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.

extmod/virtpin: Initial implementation of open-ended C-level Pin interface. Using usual method of virtual method tables. Single virtual method, ioctl, is defined currently for all operations. This universal and extensible vtable-based method is also defined as a default MPHAL GPIO implementation, but a specific port may override it with its own implementation (e.g. close-ended, but very efficient, e.g. avoiding virtual method dispatch).
