[Ovmsdev] Refactoring MODEM/SIMCOM for v3.3

I have started the work on refactoring the modem driver to support virtual driver implementations (SIMCOM 5360 being just one of them). This is a major refactoring that will take some time to complete. It is likely that the following components/files will be affected:

Component simcom (major changes)
New component ovms_modem introduced
ovms_webserver/dev/commands.htm
ovms_webserver/src/web_cfg_init.cpp
ovms_webserver/src/web_cfg.cpp
Component powermgmt
And several other components mentioning Simcom, but only very minor changes

I would appreciate it if no major changes were made to those components in the next week or two, as that may make merging difficult.

Once I’ve got the modem code refactored, and a compatible SIMCOM 5360 driver working, I’ll publish to the for-v3.3 branch for wider testing. I can then add the other modem drivers I have been working on.

Regards, Mark.

P.S. Pretty obvious that this work is to abstract out the modem type specific code, to make it easier to add support for other modem types in OVMS. This is a long-term project, and not something happening anytime soon, but I am working on it.
