This cl adds a socket pair to support the communication between recovery and minadbd. Therefore, minadbd will be able to issue multiple commands to recovery and get back the status of each command. This cl also switches the adb sideload from the recovery menu to use this protocol; and moves minadbd to a separate binary. Bug: 130166585 Test: sideload a package Change-Id: I80d36d5c4e6fe1ae3ea23640907bc50c0dc0d482
minadbd is now mostly built from libadbd. The fuse features are unique to minadbd, and services.c has been modified as follows:
- 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.
