Make all local header files self-sufficient.

Normalize order of including header files, so that header corresponding with
compilation module is included first, followed by local headers, system
headers, standard headers, and finally headers from auxiliary libraries.

Remove all include statements that are, or are made redundant by the above
changes.

Writing empty string gets ignored. This causes problems for example
when switching from mass-storage mode to charging only as the
lua/file attribute does not get cleared.

Use a wrapper function to append a linefeed to strings written to sysfs.
This avoids zero length writes and makes behavior similar to how
redirected echo from command line works.

Also tweak unexpected-sysfs-content-change tracker so that it ignores
changes in whitespace.

Configfs wants to have numbers in '0xbeef' form while android usb wants to
have 'beef'. Normalizing the output to expected format allows either form
to be used in usb-moded configuration files.

Add custom Makefile for faster smoke-test rebuilds without spending time
in configure, autotools, document generation and/or rolling rpm packages.

Add multiple include protection to all header files.

Move function prototypes away from header files that included in the
development package.

Mass rename functions to have a prefix giving context for the function.
For the most part the prefix is derived from the name of the compilation
module containing the function.

Mass normalize indentation to four spaces in all source files.

Augment author lists on each source file based on git committers.

Remove "inline" attributes from not-really-inlineable functions.

Remove .gitignore.

Remove unused modules-android.c source file.

Define _GNU_SOURCE for whole build rather than in individual files.

Fix resource leaks here and there.

Try to avoid hard-coding android usb paths.

Add configfs backend for usb cadget configuration.

Probe supported backends (configfs, android usb, or kmod) on usb-moded
startup and make them mutually exclusive with each other.

Allow configfs and android usb control structures some time to show up
if usb-moded is started during device bootup.

Refactor udev event listener to utilize a state machine. Simplifies
book keeping and makes pc/charger detection heuristics easier to control.

Refactor mode selection to utilize three interconnected mini state machines.
Allows separating logically wanted mode from mode programmed to usb and
mode exposed over D-Bus.

On some devices enumeration fails on the 1st connect after bootup unless
android usb has already been set up for some function at least once.

Add --android-bootup-function option that can be used on such devices
to force usb-moded to program some function and then clear the function
list when usb-moded is executed during device bootup.

Usb-moded does android usb initialization only if there is a non-empty
configuration block in the ini-files. This does not make sense anymore
as the values defined in the config file are used as fallback solution
if required data can't be obtained by other means.

If android_usb specific sysfs controls are present on the device, try
to initialize them regardless of whether ubs-moded configuration files
contain relevant information or not.

While android initialization scripts typically set up the usb serial number,
it might happen at wrong time from usb-moded point of view and we in general
want to minimize the amount of android init that is needed/used for running
sfos.

Use usb serial number parsed from kernel command line when initializing
default usb properties.

If android usb is in enable=0 state, cable detection is persistently
broken as the existing workarounds in usb-moded are made when cable

Seems an empty android gadget only enumerates if some configuration had
been used before. Fix this by using mass_storage to make a similar fake
mass_storage device as used with normal modules.
