Vladimir Sementsov-Ogievskiy 1ed8903916 treewide: handle result of qio_channel_set_blocking() 
Currently, we just always pass NULL as errp argument. That doesn't
look good.

Some realizations of interface may actually report errors.
Channel-socket realization actually either ignore or crash on
errors, but we are going to straighten it out to always reporting
an errp in further commits.

So, convert all callers to either handle the error (where environment
allows) or explicitly use &error_abort.

Take also a chance to change the return value to more convenient
bool (keeping also in mind, that underlying realizations may
return -1 on failure, not -errno).
