Kill of most of the remainder of minadbd.
I think everything left now is here to stay (services.c might get
massaged in to libadbd if it gets refactored).

-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
