options parsing.
Rename `options' to `long_opts'. Most things removed, as they're now handled

Add parse_opt to deal with our few meagre remaining options in the approved
options_parse manner.

initial sync interval.
|
|
initial function name argument (it's now supplied automagically).
|
|
macros that automagically supply the caller's function name, and rename the
original functions (which these macros call) to have an underline prefix.
Get rid of the CHECK_STRICT variable.
|
|
and just always do the tests it controlled.
Change uses of the ext2_{warning,error,panic} functions to not have the
initial function name argument (it's now supplied automagically).
|
|
(the previous names are now macros that call the renamed functions). Also
rearrange a bit to hold the lock around the use of the global message buffer.
