Rename the configs/stm32f0discovery board directory to configs/stm32f051-discovery.  There are others stm32f0discovery boards with different MCUs and different peripherals on the board.

* arch/arm/src/lc823450: Use spinlock APIs in lc823450_gpio.c

Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com>

* arch/arm/src/lc823450: Add a warning message in up_ack_irq()

    In SMP mode, H/W interrupts should be handled on CPU0 to avoid deadlocks.

    Other changes:
    Fix a potential race condition in up_enable_irq()
    Use spinlock APIs instead of critical section APIs.

* arch/arm/src/lc823450: Enable HRT_TIMER in lc823450_timerisr.c

    Other changes:
    Fix style violations and call up_enable_irq() to assign CPU0 for IRQ handling.
    Use spinlock APIs instead of critical section APIs.

arch/arm/src/lpc54xx:  Make the SPI driver selections EXPERIMENTAL since the SPI peripherals are not fully implemented.

arch/arm/src/lpc54xx:  Make the SDMCC driver selection EXPERIMENTAL since it has not yet been verified.

    arch/arm/src/lpc54xx:  Adds the LPC54-specific clock configuration logic to the leveraged SD/MMC driver.
    arch/arm/src/lpc54xx:  Leveraged SD/MMC driver builds without error but is still missing clock configuration logic.
    arch/arm/src/lpc54xx:  Bring in LPC43xx SD/MMC driver from https://github.com/Smoothieware/smoothie-nuttx/tree/master/nuttx/arch/arm/src/lpc43xx

Lpcxpresso-Lpc54618 and FT5x06 driver.  Some improvements in configuration and the touchscreen driver improves the behavior some.  Now I get the calibration screen and detect touches (but no un-touches).

drivers/ft5x06.c:  Add additional configuration options:  Optimize if multi-touch capability is not used.  Add options to swap X/Y and thresholding to reduce the rate of false alarm reports (with no motion).

drivers/ft5x06:  Add a polled mode of operation for the FT5x06 in attempt to work around the fact that the LPCXpresso-LPC54628 chose a non-interrupt pin for the FT5x06 interrupt.  Driver is still not yet functional.

configs/indium-f7:  None of the configurations would build because the claimed to support buttons, but the button code does not compile.  Refreshed all configurations with the configuration tools that have all become corrupted.  Somebody has been hand editing config files and fucking things up!

net/tcp: Introduce tcp receive window control based on I/O buffer

NOTE: The algorithm is still experimental but useful for http streaming.

arch/arm/src/a1x, kl, lpc11xx, lpc31xx, and nuc1xx:  Fix some compile warnings that I introduced with a possibly overzealous recent change.

arch/arm/src/sama5 and samdl:  Fix some compile warnings that I introduced with a possibly overzealous recent change.

arch/arm/src/sam34:  Fix some compile warnings that I introduced with a possibly overzealous recent change.

configs:  Still trying to get consistent name.  button driver expects board to define NUM_BUTTONS, not BOARD_NUM_BUTTONS.  That was changed in all board.h header files, but there are still references in configs/ C files to BOARD_NUM_BUTTONS

fs/fat:  Don't warn about the CONFIG_FAT_MAXFNAME being too large if long file name support is not implemented.

arch/arm/src/kinetis:  Fix some compile warnings that I introduced with a possibly overzealous recent change.

drivers/input/ft5x06.c:  Add a driver for the FT5x06 capacitive, multi-touch, touchscreen controller.  configs/lpcxpresso-lpc54628:  Add support for the the FT5x06.  Enable the driver as well as the apps/examples touchscreen test.  Untested on initial commit.

arch/arm/src/lpc17xx, lpc43xx, and stm32:  Fix some compile warnings that I introduced with a possibly overzealous recent change.

fs/nfs/nfs_vfsops.c: Correctly infer file type.  The file type is in struct nfs_statinfo_s's ns_type field, not in the ns_mode field.
