Create a cache of block data received via adb. The cache size is set
to ensure that there is at least 400mb available for the installer.
When the cache is large enough to hold the entire file, each block is
read via adb at most once.
When the cache is not large enough to hold the entire file, the cache
will need to be pruned. Because files tend to be read sequentially
during install, the pruning algorithm attempts to discard blocks that
are behind the current file position.

1. That read data will be blocked when adb sideload OTA package
2. An error(Out of bound read) occurs when installing OTA package by fuse
Test: as follows
- adb sideload OTA package
- install OTA package by install_with_fuse parameter

The expression "!fd" calls the implicit conversion to int, but comparing
the raw fd against 0 does not work, since open() and other POSIX calls
returning a file descriptor use -1 to signal an error.
Test: m recovery

It's no longer needed with the newly added FuseDataProvider class. Also
cleans up the parameters for run_fuse_sideload.
Bug: 127071893
Test: unit tests pass, run a sideload

The fuse data provider for adb/sdcard shares common code and structures.
This cl creates a FuseDataProvider base class and provides
implementations for adb and sdcard.
In the follow cls, we can kill the provider_vtab struct; and also add
another implementation to parse a block map file and provides data.
Test: unit tests pass, sideload a package, apply a package from sdcard

Move the module into a separate directory so that we can export only the
expected header.
With this change, minadbd no longer needs to include bootable/recovery.
Test: mmma -j bootable/recovery
