configure.ac: Bump libtool/library version from 1:1:0 to 1:2:0.
The libtool current:revision:age numbers change from 1:1:0 to 1:2:0
(i.e., revision is increased) since the library source code has changed,
but no interfaces were added or changed or removed.
This changes the library filename (e.g. on Linux) from libsigrok.so.1.0.1
to libsigrok.so.1.0.2, but the SONAME (+symlink) remains the same
(libsigrok.so.1) since this release is API- and ABI-compatible with the last.

Fix two FreeBSD build issues related to libusb-1.0.
FreeBSD's libusb-1.0 compatible library has a few differences compared
to the "normal" libusb-1.0 from libusb.org which we have to work around.
LIBUSB_CLASS_APPLICATION doesn't exist in FreeBSD's libusb, and
libusb_handle_events_timeout_completed() doesn't exist either.
The latter is basically libusb_handle_events_timeout() with an extra
(unused by us) parameter, so the workaround is relatively simple.

metex14: Support DMMs with whitespace differences.
Most Metex DMMs use e.g. " mV" as unit field, others use "mV ",
though. Support these (and other) whitespace variants by stripping all
spaces and only comparing non-space characters.

Bump libzip requirement to >= 0.10.
We now use zip_int64_t and zip_get_num_entries() for example, which
requires at least libzip 0.10. This version was released in 03/2012,
which is old enough that we don't necessarily have to do a work-around
for older versions. Thus, simply bump the requirement to >= 0.10.

agilent-dmm: Fix SEGV during incomplete reply from meter.
If buf contains exactly the string "Agilent Technologies" (for example if
there are bugs in the timeout logic or serial driver causing the reply from
the meter to be abridged) then this code will SEGV. This is because tokens[1]
is NULL but only tokens[2] and tokens[3] (both of which are undefined) are
NULL checked.
Can be trivially corrected by NULL checking tokens[1] as well.

serial: Only sleep when no characters are received.
g_usleep(XX) sleeps for *at least* XX microseconds but may sleep for
longers (on older kernels the sleep will typically be 10000us). Thus
byte receive loops containing an unconditional sleep will perform
very poorly (for example it causes the scan in agilent-dmm to timeout
prematurely).
Even on modern kernels serial_readline() has a 2ms sleep per byte which
means it will read at a maximum rate of half a character per millisecond
(~4800baud).
This is fixed by only sleeping when read() returns no data.
Add sr_session_append(): add captured data to an existing session file
This extends the session file format to contain logic data files named
either "logic-1" as before, or "logic-1-1", "logic-1-2", ...
representing chronologically ordered chunks of captured data.
The chunks are transparently concatenated together by sr_session_load().
This exposes the list of devices added to the session. In the case of
loading a session from file, these struct sr_dev_inst are otherwise
not exposed to the frontend. See bug 145.

Voltcraft VC-830: Fix diode mode handling.
This DMM is not using the standard bits in the FS9922 protocol/structure
to indicate the "volt" and "diode mode" flags. Instead, it only sets the
user-defined bit "z1" to indicate both "diode mode" and "volt".

Bump package version to 0.2.1, libtool version to 1:1:0.
The last release (0.2.0) had the libtool version (current:revision:age)

interfaces, only 'revision' is increased, resulting in 1:1:0.
