apps/nshlib:  Add support for a truncate command.  This will be used to test the new ftruncate file system support.

apps/netutils/ftpc:  Fix some cornercases that could cause FTP to access past the end of valid data.

Adds 'setlogmask' application that allows you to set the syslog priority via a simple command

i8shark: Fixes special XBee compensation by purposely chopping off the FCS.

apps/examples/pdcurses:  Clean up charset example so that the display geomtry  is better on very wide displays (wide with respect to the width of a character).

apps/graphics/pdcurs34:  For BPP < 8 case, correct some index and masking of final unaligned bytes.  Also corrects units used in some X conversions.  Need units of pixels, not characters

apps/examples/pipes:  Fix some kruft left in last commit;  Also clean up some coding standard problems.

apps/graphics/pdcurs34:  Correct logic that sets the font buffer to the background color for the case of BPP < 8.

* apps/graphics/pdcurs34: Initial steps to support less than 8-pixel fonts on less than 8-bit display

* pdcscrn.c edited online with Bitbucket

* apps/graphics/pdcurs34: Calculation of font buffer stride must depend on the configured BPP.

* apps/pdcurs34:  Rearrange some things so that there is slightly less conditional compilation.

* apps/pdcurs34:  Fix a misnamed label; add first cut at function to copy a font into the font buffer; Make better use of macros to reduce code complexity.

* apps/graphics/pdcurses:  Fix a few compile issues with last commit.

apps/examples/pdcurses:  Add a very simple example that just shows the entire character set (7-bit only).  It adapts to the size of the framebuffer and, hence, can be used with very tiny displays.  In fact it looks really dumb on big displays.

apps/example/fb:  Restores 0205eeef.  It was correct all along.  Also fixes calculation of the end byte position.

apps/graphics/pdcurs34: When clearing screen, width calculation should round up for any fractional bytes.  When pdcurses is closed, forgot to close the djoystick driver.
