Fix bug where leading backslash digit
in name was not being properly handled.
The reason was that I accidentally attemped to allow \x... and \0...
escapes in identifiers. This make identifiers
with leading escaped digits not work any more.
Also added test case.
Add support for embedded NUL characters
in character arrays and added some test cases.
Note that embedded NULs in netcdf-4
string constants are still illegal. This is
because strings are not counted in the netcdf
API, so they are implicitly NUL terminated.
Ncgen is unable to resolve
ambiguous references to an enum
constant when two different enums
have same econstant name.
Solved by allowing more specific
forms for econstant references.
1. /.../enumname.enumconstname
2. enumname.enumconstname
3. enumconstname
Case 1 is resolved by using the econstant
in the specific enum definition. If none is
found, an error is reported.
Case 2 is resolved by
1. finding an enclosing group with an
enum definition with the specified name
and containing the specified econstant.
If there are more than one, then an error is reported
2. finding all enum definitions in the dataset that have
the specified enum name and contain the specified
econstant. If more than one is found, then an error is reported.
If the above two methods fail, then report an error.
Case 3 is similar to case 2, but all enums, irrespective
of name are used if they contains the specified enum constant.
The ref_tst_econst.cdl test in ncdump is causing ncdump
to fail. So there may be yet some problem.
NCF-42: _Format attribute sometimes being ignored
NCF-43: Fixed unsigned long long parsing.
NCF-47: Make opendap code properly handle illegal names like "x.y" by
supressing them
NCF-49: check for uint type
NCF-50: properly handle username:pwd embedded in urls.
