New description:

 This will eventually replace b10-loadzone and revise dns++
 masterLoad().

 In the very initial phase, I propose introducing a generic lexer and
 master file parser using the lexer.  The parser initially only handles
 a limited set of entire syntax.  Then update the data source loader
 and b10-loadzone using them.  In the next phase we'll support
 more variations of master file syntax (no tickets are created for
 them).

 For the initial phase, we'll need to do:
 - generic lexer: #2369, #2370, #2371, #2372, #2373, #2374, #2375
 - generic parser: #2376, #2377 (and #2381, less important)
 - zone loader: #2378, #2379, #2380

 The following are bonus, but will be needed in later phases
 - other libdns++ objects updates: #2383 (more important/urgent), #2384
 - rdata updates: #2382, #2385, #2386, #2387, #2388, #2389, #2390, #2391,
 #2392, #2426
