Merge pull request #40 from steadfasterX/hotfix/partsize 
fix wrong part_size calculation (1 sector missing)

fix: wrong part_size calculation (misses 1 sector) 
IRC excerpt:
[12-20 15:20]  <steadfasterX> i have a partition: end=378879 start=377856
[12-20 15:21]  <steadfasterX> so the calcluation would be 378879-377856
[12-20 15:21]  <steadfasterX> which is 1023
[12-20 15:21]  <steadfasterX> which can never be correct
[12-20 15:22]  <steadfasterX> this is bc in the calculation it will need to include the start (or end) sector itself
[12-20 15:23]  <steadfasterX> when i dump without that +1 i miss exact 512 bytes so 1 sector

05564d5ffe dump-file.py: allow skipping part of a file 
Reading a file (or partition like /dev/block/mmcblk0p1) from an offset
was requested in #26.

39c9872ca0 dump-file.py: allow custom size 
Files like /proc/kmsg are reported as zero size. It can be useful to
assume a larger size to avoid empty output.

Some devices are locked down and do not support all shell commands. If
you know the size (or just want to try to read 1 byte), then you can
avoid executing shell commands.

114f2b3cd8 Reading is a lossed art, be more consistent with existing stuff 
Upon looking, it seems the H962 has idProduct identical to the D855.
Note in appropriate places the H962 is now supportted.

81998e1dde Add one varient of the LG V10 to the usb.rules file 
Now we can talk to another LG device.  This device though does need the
protocol fix (issue #7) solved before becoming truly useful though.

688e0f3d17 lglaf.py: Fix "Resource busy" error 
Detach kernel driver (cdc_acm) to avoid this error:

    usb.core.USBError: [Errno 16] Resource busy

Deliberately do not call attach_kernel_driver for the detached devices,
it is likely that the user runs lglaf multiple times. The user can
unplug and re-insert their device if they want to re-attach the kernel
driver.

f2792e6374 lglaf.py: dynamically query for endpoint numbers 
The endpoint numbers are apparently not fixed. Use heuristics to

396409d3fa Make shell execution a bit more reliable 
Previously you would not get feedback when quotes are not terminated or
when the command is too long. Fix this by putting stderr redirection in
the shell command, before eval.

90d89bbe5f Add full LG4 (VS986) support 
Add productId to the Wireshark dissector and udev rule, adjust the
serial path detection logic to find the right key
(`\Device\LGVZANDNETDIAG1`). Now you do not need to pass `--serial COM4`
anymore.

Reportedly fails in VirtualBox with USB passthrough, but works fine on
Linux. Thanks @invisiblek for testing!

2d79e1565e Attempt to LG G4 compatibility 
lsusb from @invisiblek, unfortunately it seems to hang when used in
VirtualBox (USB passthrough from Windows to Linux).

The second CD of exposes the endpoints over bInterfaceNumber 2, so this
patch simply activates the second CD.

e71375d6cc lglaf.py: do not hang forever on reads 
Use 5 second timeout for the initial hello and 60 seconds for other
cases. Maybe a --read-timeout option should be added in case you need
more time...

a1208e6723 Improve INFO GPRO field 
Not just the first two bytes should match, it should be the expected
length. Found the hint in dmesg after failing to retrieve the properties
file. Setting all following bytes to 0xff does not seem to affect the
output, so let's keep it like this. The original software does send an
empty buffer though (with all zeroes).

d26f0717a9 Add support for VS985 and others 
The udev rules and Wireshark dissector still have idProduct hardcoded
for the time being, but lglaf.py detection logic is converted to use
heuristics instead.

ab642bd7c0 protocol.md: update erase, read, exec 
Thanks to hints from /proc/kmsg, I found the IOCTL_TRIM_CMD (0x1277)
hint. From the kmsg, the meaning of "LAF" was also found (which could be
discovered via the lafd binary too...).

The whence option for read was observed by putting 0xffffffff in the
argument and was tried because the DLL showed a fourth argument that was
always zero.
