e157b253d4 Fix sdcard logging.
Use C++ logging for everything.

714ec9d1de sdcard: Fix compilation with FUSE_TRACE == 1.
"PRI{u,x}64" was not compiling on C++ because of macro expansions.
Implement DLOG the same way DCHECK is implemented in
<android-base/logging.h>, and mechanically replace the problematic
lines with C++ logging. Remaining TRACE() lines will be replaced in a
follow-up CL.

d6d8faa690 sdcard: Use std::map.
Having CaseInsensitiveCompare use strcasecomp is not ideal, but other
solutions are not prettier.

Also, add a TODO to fix FUSE_TRACE, broken by the switch to C++.

f08ba05581 Convert fuse.c to C++.
Fix string literals and cast void* appropriately. Alternatively, we
could switch some of the allocations to new/delete, but we would need
to make sure that none of those end up passed to other code that will
call free(3) on them.

c255f25ccb Extract the FUSE implementation from the main sdcard.c file.
sdcard.c is a *really* big file. This makes it hard to do things like
improving priv dropping or adding more sandboxing. Extract all
FUSE-related code to a separate unit, fuse.{h|c}, which exports only
two functions. Convert the rest of sdcard.c to C++ as sdcard.cpp.
fuse.c is kept as C (at least for now) since interacting with the FUSE
API is realistically easier from C.

60281d556d Use bionic's <linux/fuse.h>.
No need for an out-of-date copy of a uapi header.

03ee9479a4 sdcard: a program to create a "virtual" /sdcard pointed at a path
sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
directory permissions (all files are given fixed owner, group, and
permissions at creation, owner, group, and permissions are not
changeable, symlinks and hardlinks are not createable, etc.

usage: sdcard <path> <uid> <gid>

It must be run as root, but will change to uid/gid as soon as it
mounts a filesystem on /sdcard.  It will refuse to run if uid or
gid are zero.
