- if somebody puts a "%" into the delimiter on the command line bad things happen.

- regarding nvals

- regarding dsave by deleting the code.  it shouldn't be needed, probably won't hurt.  "make check" passes.

the base64 codec we were using was GPL, which is compatible with metaio's
license *except* that metaio includes the code for a matlab extension
module.  the authors of metaio can choose to link their own code to matlab,
but doing it to someone else's GPL'ed code is a license violation.  luckily
I found a public domain codec, but it does less error checking so we loose
that.

- bump version to 8.4.0
- update daswg e-mail address
- remove obsolete check for size of size_t

- make metaio_test.sh a script that isn't constructed by config.status (so it's execute flag can be set)
- and fix paths to test files

gzvscanf() was using global static data for a buffer.  this patch moves it onto the stack
