This CL mainly changes:
a) moving the interface in struct provider_vtab to std::function;
b) code cleanup, such as moving the declaration closer to the uses,
using explicit type conversion.
Test: recovery_component_test
Test: minadbd_test
Test: Sideload a package on marlin.

We might end up in an infinite loop if read(2) reached EOF unexpectedly.
The problematic code in uncrypt mentioned in the bug has been fixed
by switching to libbase ReadFully(). So I grepped through the recovery
code and fixed some other occurences of the issue.

For applying update from SD card, we used to use a thread to serve the
file with fuse. Since accessing through fuse involves going from kernel
to userspace to kernel, it may run into deadlock (e.g. for mmap_sem)
when a page fault occurs. Switch to using a process instead.
