Simon McVittie requested to merge smcv/dbus:dbus-send-validate into master Jun 21, 2021

dbus-send: Print an error message if object path is syntactically invalid
```
  $ dbus-send // nope
  Object path was not valid: '//'
```
Related to #338 (closed).
dbus-send: Validate interface, member names before use

Instead of a failed check or assertion failure and a core dump, let's produce an error message on stderr and a graceful nonzero exit status. It's still not going to work, but at least we can avoid crashing.
```
  $ dbus-send / com.example.Nope..Nope
  Interface name was not valid: 'com.example.Nope.'
  $ dbus-send / com.example.Nope.0
  Invalid signal name: Member name was not valid: '0'
```
Resolves: #338 (closed)
