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
