Call access(2) on all files/dirs modified by Mtp
External sdcards are accessed through /mnt/media_rw,
so access() each touched file for sdcardfs to update
its metadata. This is done for all created/deleted/renamed
folders and files.
Bug: 77849654
Test: use mtp with emulated sdcard

MtpServer changes for MtpStorageManager
MoveObject and DeleteObject require
begin() and end() methods in order to
maintain database consistency. delete() now
has to return errors.
Allow sendObject after sendObjectInfo since
the spec allows this.
Test: See tests for main MtpStorageManager change

Account for folders in copy and move.
Copy and move will use mkdir() if target
is a folder, and copyFile() if target is a file.
Move will recursively copy contents if moving
between different storages. Move will also
change the storageId.

Test: Copy and move folders on win 10

Add implementations for move and copy operations.
Previously, we didn't have these implemented so the
host OS would emulate them by pulling the object
and pushing it to a new location. This can result
in data being lost and it is slow.
With the operations implemented, moving objects
on the same storage is instantaneous since the data
doesn't need to move. Moving objects between storages
and copying objects are both much faster since no
data has to be moved through USB.
Bug: 66679910
Test: Move and copy objects, verify they are correct

Checkpoint work on MTP and PTP investigation.
This change includes work in progress on a C++ library for both host and device
MTP and PTP support.
Currently the makefile builds two test programs:
mtptest - a command line test program that implements a small subset of device side MTP.
Requires a kernel driver that has not been checked in yet.
ptptest - a host tool to test USB host support for detecting and communicating with
digital cameras over PTP. Runs on Linux host.
Later this will be reformulated as a native library that will be used in the media process.
