instead of sending 12 byte header in a separate packet.
PTP on the Mac is much happier with this approach.

These calls did not correctly handle some variants of the arguments,
which showed up when running in PTP mode.

MTP does not support partial writes of files (the entire file must be transferred at once).
This makes it impossible to implement a FUSE file system for MTP
with acceptable performance.
To fix this problem, this change adds extended MTP operations to allow
partial writes to files:
SendPartialObject - allows writing a subset of a file, or appending to the end of a file
TruncateObject - allows changing the size of a file
BeginEditObject - must be called before using SendPartialObject and TruncateObject
EndEditObject - commits changes to a file after it has been edited with SendPartialObject or TruncateObject
We also add GetPartialObject64, which is the same as GetPartialObject
but has a 64 bit offset rather than 32.

Set resource config_mtpReserveSpaceMegabytes to number of megabytes to reserve.
If MTP has dedicated storage this value should be zero, but if MTP is
sharing storage with the rest of the system, set this to a positive value
to ensure that MTP activity does not result in the storage being
too close to full.

Now the file copy is done completely within the media process
rather than pushing data to the client via ContProvider.openFile().
File system writes are now interleaved with USB reads, which allows us
to copy the data faster and prevents the camera from timing out during transfer.
File is automatically inserted in the media provider after a successful import
and a Uri is returned to the client.
