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.

(I'm going through all of frameworks/base in multiple passes. This pass is just
for exception throwing.)
