I could fix the problem that infos may appear on the alias dbRecordNode,

but to allow 'caget alias.info' I needed dbRecordNode.aliasedRecnode

which Michael introduced in 3.16(?). Thus it would make sense to

implement CA to info fields in 3.16+ only, right? For my tests, I have

simple back-ported aliasedRecnode to 3.14.12.7.

One thing is a bit confusing at them moment:

When a record has infos and aliases, the infos are bound to the previous

alias, not to the original record:

record (ai, "dz:ai")
{
  alias("alias1")
  info(my_info_field, "Hello World")
  alias("alias2")
}
alias("dz:ai","alias3")

epics> dbla
alias1 --> dz:ai
alias2 --> dz:ai
alias3 --> dz:ai

epics> dbli
alias1.my_info_field "Hello World"

$ caget dz:ai.my_info_field
Channel connect timed out: 'dz:ai.my_info_field' not found.

alias1.my_info_field           Hello World

$ /usr/local/epics/base/bin/SL6-x86_64/caget alias3.my_info_field

Need to fix that...
