util: raise ParseError when parsing dates (BC)

a7dce526c462 refactored util.parsedate in order to raise ValueError instead
of Abort for using with ui.configwith. It causes several problems, putting
arbitrary bytes in ValueError can cause issues with Python 3. Moreover, we
added a function to convert ValueError exceptions back to Abort.

A better approach would be to make parsedate raises ParseError, removing
the convert function and update configwith to also catch ParseError.

The side-effect is that error message when giving an invalid date in CLI
change from:

  abort: invalid date: 'foo bar'

to:

  hg: parse error: invalid date: 'foo bar'

I'm not sure if it's an acceptable change, I found personally the error
message more clear but more verbose too.

Just exercise debugindexdot
Create a short file history including a merge.
  $ hg init t
  $ cd t
  $ echo a > a
  $ hg ci -qAm t1 -d '0 0'
  $ echo a >> a
  $ hg ci -m t2 -d '1 0'
  $ hg up -qC 0
  $ echo b >> a
  $ hg ci -m t3 -d '2 0'
  created new head
  $ HGMERGE=true hg merge -q
  $ hg ci -m merge -d '3 0'

  $ hg debugindexdot .hg/store/data/a.i
  digraph G {
  	-1 -> 0
  	0 -> 1
  	0 -> 2
  	2 -> 3
  	1 -> 3
