Bump libtool version (not package version) to 3:0:0.
The last release (0.3.0) had the libtool version (current:revision:age)
set to 2:0:0. Since this release removes and changes interfaces, the new
version is 3:0:0.
This changes the library filename (e.g. on Linux) from
libsigrokdecode.so.2.0.0 to libsigrokdecode.so.3.0.0, the SONAME
(+symlink) becomes libsigrokdecode.so.3.

uart: Optimize handling of samples when tx and rx are both idle
Re-enable the fast path for identical samples but only when both
pins are waiting for the start bit. For sparse data sets (I tested
UT61E capture log) the optimization results in a >4x decode
improvement.

arm_itm: Use objdump instead of addr2line.
This improves speed and fixes bug 564. Code is somewhat
of a copypaste from the arm_etm counterpart, but there
are enough differences that it is easier to keep separate
copy of the objdump parsing in each.

usb_signalling: decode RESET and Keep-Alive signalling conditions
Resets are at least 10ms at the root hub downstream facing port and
2.5us at the device (root hub reset may be shortened by itermediate
hubs).
Keep-alive is a low-speed only signalling condition, as low-speed has no
SOFs to inhibit devices to enter suspend

Python: Restrict code to stable ABI subset
Limit usage of the Python C API to the stable ABI subset as defined
by PEP 384. This removes some type definitions and functions which
libsigrokdecode made use of. Convert all affected code to suitable
API alternatives. Also fix a few leaks that became apparent while
working on the code.
The most visible change is that PyTypeObject is now an opaque type.
Thus, the custom Decoder and srd_logic types are now created on the
heap via an alternative API. Unfortunately, since tp_name is now
inaccessible, type names had to be removed from the log output.
Stack traces after Python exceptions are now formatted by calling
into Python, since the trace object C API is no longer available.

usb_signalling: Track USB symbol width to compensate frequency errors
USB low/full speed allows for frequency tolerance of 1.5%/0.25%. At
maximum packet size (sync + PID + data + CRC16) of 12 bytes/1027 bytes
this amounts to 1.4 bits/20 bits, so the decoder has to lock to the
actual symbol frequency to avoid any symbol misdetections.
The signal is sampled twice, once at the symbol center and once at
the expected edge position. Comparing the symbol at both positions gives
an indication if the current bit width is too low or too high. Adjust
accordingly.

jtag_stm32: Fix incorrect handling of registers.

Pass unitsize per sample chunk.
Don't pass unitsize to srd_inst_channel_set_all(), have that only
set the channel map. Instead, srd_session_send() now has a parameter
for the unitsize which is passed with every new chunk to be decoded.
This is in preparation to fix issues with devices or files which
have a unitsize != 1 and where the "guessed" unitsize based on the
number of channels is not correct.
This also allows for (potential) future changes where every chunk can
indeed have a different unitsize.
