Log Message:
tio: update to 1.35.

Changes since tio v1.34:

 * Add support for automatically generated log filename

   Automatically generate log filename if none is provided.

   The auto generated file name is on the form:
   "tio_DEVICE_YYYY-MM-DDTHH:MM:SS.log"

 * Add support for configurable timestamp format

   Also changes default timestamp format from ISO8601 to classic 24-hour
   format as this is assumed to be the format that most users would prefer.

   And reintroduces strict but optional ISO8601 format.

   This feature allows to easily add more timestamp formats in the future.

 * Reintroduce asm-generic/ioctls.h

   It is needed for ppc builds.

 * Add macro hack to workaround older buggy glibc

Robey Pointer:

 * Add support for high bps on OS X
