Disable drivers that need serial port support if libserialport is not found.
Also, disable building various other serial port related code in that case.
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.
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.
The last release (0.2.0) had the libtool version (current:revision:age)
set to 1:0:0. Since this release doesn't add/change/remove any
interfaces, only 'revision' is increased, resulting in 1:1:0.

Frontends using libsigrok don't need to be recompiled or relinked.
These two drivers are currently unfinished and don't work, so disable
and "unhook" them for now in preparation of the next libsigrok release.
They're still in the git repository, but not hooked up to the build
system, so that they won't get detected or built, and also don't end up
in the release tarball.
Since link-mso19 is the only driver that currently requires libudev,
drop any reference to that, too.
It should be relatively easy to apply this patch in reverse after the
release to bring back both drivers.

When checking architecture-specific things, always check $host, i.e. the
architecture we're building _for_, not the one we happen to build _on_.
E.g. when cross-compiling _for_ Android (or Windows or others) it's important
to check for Android in $host; whether we happen to cross-compile _on_ a Linux
or Windows or OpenBSD or FreeBSD machine ($build) doesn't matter, only the
fact that we compile _for_ Android is important for most checks.
