- use pragma to handle different behavior between gcc and minGW bit-field packing
- bit-field integer variables needs to be align to 2-byte boundary
Compiler does not produce an error when accessing into non-__packed pointer.
However, the field might not be properly aligned for this type.

Before this change, the loglevel check would only be performed for the
default log handler in libsigrok, but not for other handlers set
via sr_log_callback_set().
This fixes bug #698.
A local buffer was too small, snprintf() was used to write the
name of the analog-1-1-xxx ZIP archive names in that buffer.
Due to the limited size, only 3 characters were usable for the last
number component, i.e. the code would loop around from analog-1-1-999
to analog-1-1-100 (instead of analog-1-1-1000).
As a quickfix, increase the buffer size by a large margin, a nicer
fix should be used later on.
These trigger quite often with unrelated devices and confuse people.
scpi_usbtmc: Failed to get configuration descriptor: LIBUSB_ERROR_NOT_FOUND, ignoring device.
The Modbus RTU implementation was inappropriately returning lengths
from the serial functions when the calling functions expect only an
sr_error_code value.
Make sure to not exceed the ctx->analog_samples[] array bounds. Don't
use the (huge) channel's index in the device's(!) channel list, instead
use the zero-based and dense index into the array of analog samples in
the accumulation buffer, before writing to the external file.
This fixes the segfault reported in bug #1124.
The process_analog() logic is rather complex, dealing with the total
list of channels in the device (which can be of different types), and a
number of submitted samples for a specified list of channels. Replace
the rather short variable names for i, j, c (and num_channels) with
something longer that hopefully increases readability of the complex
loop bodies.
Note that this change merely renames identifiers, and does not change
behaviour.
Instead of nesting indentation levels upon equality of a value, skip
iterations upon inequality. This reduces indentation, and might improve
readability.
