Squashed commit of the following:
fs/cromfs: Now depends on EXPERIMENTAL because it is not yet verified.
fs/cromfs: This commit brings the CROMFS file system to code complete. Still completely untested. Next steps: Need a tool to generate CROMFS file system images and a test case under apps/
fs/cromfs: Add logic to traverse the in-memory file system nodes.
fs/cromfs: Add initial support for an in-memory, compressed, read-only file system.
arch/arm/src/stm32/lowputc: fix uart glitch when lowputc is enabled
Calling up_lowputc() when a character is in the shift register results
in corrupted character on stm32f1xx and stm32f205 cores.
TC status bit ensures that up_lowputc() waits for an on-going
transmission to complete before writing in TDR.

net/tcp: Add logic to send probes when SO_KEEPALIVE is enabled.
net/tcp: TCP socket should not have to be connected to configure KeepAlive.
net/: Add a separate configuration to enable/disable KEEPALIVE socket options.
net/tcp: Arguments to TCP keep-alive timing functions probably should be struct timeval as are the times for other time-related socket options.
net/tcp: Fix a backward conditional
net/tcp: Add some more checks and debug output to TCP-protocol socket options.
net/tcp: Cosmetic changes to some alignment.
net/: Adds socket options needed to manage TCP-keepalive and TCP state machine logic to detect if that the remote peer is alive. Still missing the timer poll logic to send the keep-alive probes and the state machine logic to respond to probes.
drivers/lcd/ft80x: ACTIVE host command appears to be formatted differently than other host commands; Fix ROM CHIPID. Appears to be big-ending, BCD.
drivers/lcd/ft80x: Fix some compile issues when debug features are enabled.
Feature pca9540bdp i2cmultiplexer
* Implement common i2c multiplexer abstraction to be reused by i2c multiplexer devices. Provide common interface with transfer and reset calls to set up virtual i2c busses.
* Remove i2cmux_lower_half.c and headers, will be implemented by each mux driver
* Implement PCA9540BDP I2C multiplexer lower half which uses the common i2c mux abstraction
* Remove application interface and implement common i2c functions
* Remove application interface from pca driver and implement common i2c functions directly in the pca driver
* Use i2cerr
