phases: check HG_PENDING strictly
Before this patch, checking HG_PENDING in phases.py might cause
unintentional reading unrelated 'phaseroots.pending' in, because it
just examines existence of HG_PENDING environment variable.
This patch uses txnutil.trypending() to check HG_PENDING strictly.
BTW, this patch may cause failure of bisect in the repository of
Mercurial itself, if examination at bisecting assumes that an external
hook can see all pending changes while nested transactions across
repositories.
This invisibility issue will be fixed by subsequent patch, which
allows HG_PENDING to refer multiple repositories.
