For PVXS, field name conformance is only enforced for locally defined
types.  I've added a test to check that an "in-valid" field name can be
decoded, and re-encoded (eg. by a PVA gateway).  Some non-conformant
names won't be accessible locally though.

https://github.com/mdavidsaver/pvxs/commit/2ab0d662bf3f74f32915d0e07383d8c30217fdd5

I don't have time at present to do this testing for pvDataCPP/AccessCPP,
pvDataJava/AccessJava, or Kay's new PVA.

Title:
  Invalid charactor in field name

Status in EPICS Base:
  New

Bug description:
  When creating a group in QSRV, the allowed characters are too
  restrictive

  error:
  Error Group not created: Invalid charactor '-' (45) in field name "BI02-TimeRise" must be A-Z, a-z, 0-9, or '_'

  expected behaviour:
  pva structures should allow for a more liberal set of characters that just what is covered by \w regex metacharacter.
