Netflix reported that after pulling power while their app is active,
the app isn't able to restart. This is because the license file for
session keys isn't getting synched to disk, so the data is still in
the buffer cache when the device shuts down. Calling fflush and fsync
on the file ensures the data is persisted to disk. fclose alone
doesn't do fsync.
In testing, I also noticed that the license file was being rewritten
every second which is hard on the flash filesystem. The timer thread
was modified to avoid these frequent writes.

If the level 1 oemcrypto library loads and initializes, but has the
wrong version or does not have a valid keybox, then the level 3
fallback is used. However, in those cases, the level 1 was not
terminated properly. This caused a resource leak on some platforms.
With this CL, in OEMCrypto_Initialize, the level 1 library Terminate
is called if its Initialize was called and the level 1 library will
not be used.

If a key query occurred before a license was received an UNKNOWN_ERROR was
returned. This now succeeds but returns no information (an empty container).
Also licenses that were already expired when received were not marked as such.
This did not cause violations in playback rules but caused an exception when
they were queried.

The function rand() was not available on the mips build used to
generate the level 3 oemcrypto fallback library. This function has
been replaced by the openssl RAND_bytes(), so that compilation may
complete.

This project is still using stlport (without telling the build system
about it), which was causing (broken) stlport headers to override
libc++ headers, leading to a broken copy of std::enable_if, which in
turn caused <atomic> to fail to compile. Since this project has
prebuilts that will need to be updated before this project can
actually move away from stlport, tell the build system that it is
still using stlport for now.

OEMCrypto may report an HDCP status of "No HDCP device attached/using
local display with secure path". This is not propagated upto
the server as an appropriate HDCP value did not exist in the
license protocol. This has now been added. Netflix has requested that
this be reported.

The OEMCrypto did not save the usage table correctly after a key was
loaded and not used.
Also, oemcrypto uses the keybox to verify and sign the usage table.
On library initialization, the usage table was being loaded before the
keybox, so the signature was not verified correctly.
Both these problems have been corrected.
