		The contents of this directory are copied from system/core/adb, with
		the following changes:
		minadbd is now mostly built from libadbd. The fuse features are unique to
		minadbd, and services.c has been modified as follows:

		adb.c
		- much support for host mode and non-linux OS's stripped out; this
		version only runs as adbd on the device.
		- always setuid/setgid's itself to the shell user
		- only uses USB transport
		- references to JDWP removed
		- main() removed
		- all ADB_HOST and win32 code removed
		- removed listeners, logging code, background server (for host)

		adb.h
		- minor changes to match adb.c changes

		sockets.c
		- references to JDWP removed
		- ADB_HOST code removed

		services.c
		- all services except echo_service (which is commented out) removed
		- all services removed
		- all host mode support removed
		- sideload_service() added; this is the only service supported. It
		receives a single blob of data, writes it to a fixed filename, and
		makes the process exit.

		Android.mk
		- only builds in adbd mode; builds as static library instead of a
		standalone executable.

		sysdeps.h
		- changes adb_creat() to use O_NOFOLLOW

		transport.c
		- removed ADB_HOST code

		transport_usb.c
		- removed ADB_HOST code
