icetime: Add support for searching for chipdb relative to binary

Like yosys and arachne-pnr, allow for searching for the desired chipdb
file relative to the executing binaries directory. This allows for
portable builds of icetime without needing to specify the exact path to
the needed chipdb file with the -C arg.
In order to support this icetime must be able to get the
"proc_self_dirname" path just like yosys and arachne-pnr. As such copy
the equivalent code to get this path information. To avoid cluttering
the icetime.cc file with this code, place it in a separate iceutil.cc
file.

In cases when the FLASH chip is bit flaky and the status register
"bounces" this flash_wait should be able to perform a bit better.
Also added more verbose output around block erase.

Very useful for debugging purposes. ;)
|
| | | |

The function now checks how long the extended JEDEC ID field is for the
particular FLASH chip and only reads the amount provided by the chip.
|

I missed those the first time around.

Just calling a gpio function with two numbers was not very self
explanatory. The functions now refer to the actual indended action, chip
(de)select for flash, reset and chip (de)select for sram. Reading the
code and understanding what steps are taken should be easier now.

Main point was to group the code into three logical segments:
* MPSSE/FTDI defines and functions
* FLASH defines and functions
* iceprog implementation core
While I was at it I also added a few comments for stuff that was not
immediately obvious what it does.

icebox_hlc2asc: fix _lut_ keyword parsing
|
| |
| |
| |
| | |
'self.lut_bits is None' was always false. The _lut_ keyword is used by asc2hlc, so when converting asc->hlc->asc the lut_bits were always all zeros.

Previously if you were doing;
`icebox_vlog example.asc > example_bit.v` you would just get;
```
Traceback (most recent call last):
File "icebox_vlog.py", line 947, in <module>
assert False
AssertionError
```
Now you get;
```
Traceback (most recent call last):
File "icebox_vlog.py", line 948, in <module>
assert False, "\n ".join(emsg)
AssertionError: Single-driver-check failed for 2 nets:
