Without a SR_DF_END samples could be cached in the internal buffer of an output
module and never flushed, therefore they would be missing in the final output.
By sending a SR_DF_END packet we force the output to be flushed.
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.
The bandwith in Rigol DS1xx2D/E scopes can be upgraded to 150 MHz in software.
So detect also scopes with the upgraded bandwith.
