`g_assert_true' and `g_assert_false' are defined in glib 2.38 or later.
The minimum glib version currently required by ModemMamanger is 2.36.
While `g_assert_true' and `g_assert_false' may be preferred over the
more generic `g_assert', it seems like overkill to bump the minimum glib
version requirement just for that. When more code in ModemManager later
requires newer versions of glib, we can migrate all existing code to use
`g_assert_true' and `g_assert_false' when appropriate.
In place of two slightly different regexes for 2g/3g and 2g/3g/4g modems
we now use only one regex with conditional patterns for both supported
and current Bands detection.
Adding also minor fix in test code
GE910 is a 2g only modem and when queried for bands it returns
only a 2g set of bands:
--> 'AT#BND=?<CR>'
<-- '<CR><LF>#BND: (0-3)<CR><LF><CR><LF>OK<CR><LF>'
Current regex fails, since it considers the 3g bands block mandatory.
A similar problem happens for current bands.
This patch modifies the regular expressions for properly
supporting GE910 and updates tests.
