Bugfix/spitool exch parse txdata
* friendlier I2C "knock-knock" uses only read request
While many I2C slave devices have multiple indexed registers, some have
only one register and it's not indexed. For example, the I2C bus switch
TCA9548A has only a Control Register, attempting to index to "Reg[0]"
alters its contents to 0x00 disabling all subordinate buses. This patch
fixes that problem by simply trying to read something/anything from the
slave. This also helps coax out slaves with register files that start
from a higher index, i.e. the AT24CS0x, FLASH chips with a UUID that
appears as a 2nd I2C slave at (address+8), report their serial number at
Reg[80]-Reg[8F] and will NAK a read of Reg[0].
* modify get/set to prevent write of reg index if not specifed
* correctly parse exch txdata args, if any
* should always call the board's deselect

* modify get/set to prevent write of reg index if not specifed
* add 'dump' command to issue a single transaction
to retrieve multiple bytes from an I2C slave and register/offset.
* use NuttX' isprint()
* refactor to reduce coupling, hexdump only needs outstream

1. Check NSH_NETINIT for self network initialization
2. Check NSH_ARCHINIT for sel arch specific initialization
3. Always show help regardless of NSH_BUILTIN_APPS
4. Loop forever regardless of NSH_BUILTIN_APPS, user could:
a.change the default behavior by the command line argument
b.or ctrl+c to break out the loop

include/ and netutils/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
nshlib/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
system/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
testing/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
examples/: Remove references to CONFIG_DISABLE_SIGNALS. Signals can no longer be disabled.
Squashed commit of the following:
apps/nshlib: Remove NSH initialization. Now uses the common apps/netutils/netinit logic (which was cloned from nshlib to begin with).
apps/netutils/netinit: Clone network initialization logic from NSH to this directory so that it can be available for general use.
apps/system/nxplayer: Fix some logical errors from recent comments. They broke the build of the nxplayer as a library vs. a task. apps/graphics/nxglyphs: Fix yet more namespace problems.
graphics/nxwm/src/nxwm_main.cxx: Move from graphics/nxwidgets/UnitTests/nxwm/nxwm_main.cxx.
apps/graphicx/nx*: Fixes numerous build issues mostly associated with include paths and namespaces.
apps/nxglyphs: Decouple (mostly) from nxwidgets and nxwm so that they can be used elsewhere. Creates include/graphics/nxglyphs.h
apps/graphics/nxglyphs: Put all NxWidgets and NxWM glyphs into a common directory where they can eventually be shared. Not very sharable at the moment due to header file entanglements. Need a separate nxglyps.hxx header file.
Separate nxwidets and nxwm into separate directories. Remove old, common NxWidgets directory.
