Apparently, doing too large read/write I/O on the MPSSE fills up the RX Buffer
of the chip, resulting in STALL/NAK of additional transactions of an OUT request.
Since the OUT request is issued synchronously, an appropriate IN request cannot
be issued, resulting in a deadlock.
This problem is handled by submitting small enough OUT requests, that will not
fill up the RX buffer and interleaving them with IN requests.

This includes adding libftdi1 to configure.ac and Makefile.am.
avrftdi code is changed to use libftdi1. At the same time device
discovery is moved to libftdi1. Some error and debug messages in
avrftdi are corrected and/or updated. avrftdi_print is updated,
to print all messages whose verbosity level is less or equal to
the global verbosity level, so that messages with level 0 are always
printed.
This change is tested on OS X 10.6.8, Ubuntu 12.04.2 and Win7 x86_64.
The Win7 version was cross-compiled on OS X 10.6.8.

Bugfixes:
-remove ftdi_usb_purge_buffers(), since it does not flush, but clear buffers
-fix bad polling in avrftdi_flash_write() where it was possible to poll a 0xff
value.
Maintenance:
-use #defines from libftdi for MPSSE commands where applicable
-reformat E() and E_VOID() macros
-remove TYPE_* macros
-clean up private structure (remove pin_inversion, type and ftype)
-adds ftdi_pin_name() to turn a (FTDI) pin number to a human readable string
-adds avrftdi_print to encapsulate "if(verbose > c) fprintf()"-idiom
-nicer / better understandable (I hope) output
-removes pin_limit() and adds a member in the private data structure.
TYPE_* macros can be removed; decision is made from (struct ftdi_context).type
-add_pin(s)() functions reworked. parameters are validated first, if everything
is alright, pin_value is modified. pin_inversion mask is not needed; use
PIN_INVERTED instead
-change set_pin(s)(), so that it gets the pin value used by avrdude (and not a
bit mask). This way, PIN_INVERTED is usable and pin_inversion is not needed.
Plus, the interface is consistent with the add_pin() signature. Also move
parameter validation to the start of the function. I also commented out the
warning, that a pin is not defined, because it is annoying.
-clean up avrftdi_open(): first parameter validation, then USB lookup, interface
initialization then pin setup
-avrftdi_eeprom_read/write() and avrftdi_flash_read/write(): convert to new
calling scheme, where every paged_* function is called once for every page

Renames pin_name() from avrpart.c to avr_pin_name() and adds a
(globally visible)declaration in avrpart.h
The function takes an integer argument from the pin-enum in pindefs.h and
converts it to a string. The returned string corresponds to the pin names used
in avrdude.conf.
