Squashed commit of the following:
libnx: Need to duplicate some Kconfig setting for NXFONTs if it can be configured and built independently of NX. Also includes some build-related fixes.
configs/sim: Disable NX graphics support in the fb configuration.
libnx: Basic configuration and build changes to support building font support independend of the NX server.
RNDIS support on STM32F4Discovery
* stm32f4discovery: Add stm32_netinit.c to avoid a compilation error
* stm32f4discovery: Add rndis initialization in stm32_bringup.c
NOTE: MAC address for the host side starts 0xaa. This assignment
scheme should be fixed later.
* stm32f4discovery: Add rndis configuration
NOTE: STM32F4Discovery + DM-STF4BB
* drivers/usbdev/rndis.c: Fix some issues in rndis.c
Introduce rndis_transmit() and change rndis_rxdispatch() to avoid
packet corruption. Introduce max packet size for dual speed which
is mainly used for high speed mode. Fix adjusting MTU warning
on Linux host. Fix data corruption if a packet size excceds MTU.
NOTE: Max packet size is not configured dynamically. This should
be fixed in the future version.
* stm32f4discovery: Modify #ifdef condition for rndis in stm32_bringup()
* drivers/usbdev/rndis.c: Change HPWORK to ETHWORK
* drivers/usbdev/rndis.c: Merge the commit 07b98ccbb5
Previous commit b09365784a was based on old rndis.c thus resulted
in reverting the commit 07b98ccbb5. This change merges the commit.
NOTE: In the commit 07b98ccbb5, max packet size of bulkout was
assumed to be 64. In this commit, priv->epbulkout->maxpacket is
used instead.

configs/stm32f429i-disco/ltdc: This configuration has been deleted because it violated the portable POSIX OS interface. It used apps/examples/ltdc and include ltdc.h and dma2d.h which were also removed for the same reason.
This conversion is unfortunate in the sense that Unix local domain sockets are relatively lightweight. LocalHost UDP sockets are much heavier weight since they rely on the full UDP stack. If anyone is up for a complete redesign, then using some shared memory and a POSIX message queue would be lightweight again.
This commit also fixes several bugs that were not testable before the inode tree deadlock. I cannot say that the logic is 100% stable but it does not have basic functionality.
Squashed commit of the following:
fs/userfs: Order locking so that access to the shared I/O buffer is also locked.
fs/userfs: Converts to use LocalHost UDP loopback for IPC.
