Fix bug in gpio_set not setting reserved pins correctly

Loop going over reserved pins was not going over all entries as result of incorrect sizeof

Fix bug in gpio_set not setting reserved pins correctly
Removed redundant label TARGET_LPC81X_COMMON
Added preliminary support for nRF51822 as a target

No actual files for the target, just the target definition for now, so it
can't be compiled yet.
Added support to export mbed special .bld and .lib files
Added support to export repositories for seamless offline setup
Merge branch 'master' of https://github.com/mbedmicro/mbed

Exporter features

Drop deep repository scanning from scan_resources() so it doesn't affect compile
Implement repository scanning through __scan_all() for exporter
Merge pull request #108 from ScreamerBG/master

Refactored exporter features
Added LPC4088_EA to the list of targets
Added export maps

Since some targets with different names use the same exporters (for example
LPC4088_EA and LPC4088), add an "export map" for this situation.
Increase available RAM for RTX on LPC11U24

The INITIAL_SP value used by RTX was originally at the 4k limit instead
of at the 8k limit.  The HEAP_START macro was defined to __HeapLimit
but the heap really starts at __end__.  __HeapLimit is just used for
some link time sanity checks to verify that the heap and stack can
grow a bit without colliding.

support GCC_ARM for LPC4330_M4

 - Linker script is based on LPC1768
     number of NVIC is 16 (CORE) + 53 (M4 in LPC43xx) = 69,
    therefor, reserve at the top of RAM0 (address:0x10000000)
    to relocate NVIC vector table
 - startup file is based on startup_ARMCM4.S in CMSIS V3.20
     change NVIC name for cortex-M4 of LPC43xx
 - add GCC_ARM for LPC4330_M4 in python scripts
 - add some descriptions for GCC_ARM
