sslutil: make cert fingerprints messages more actionable

The previous warning and abort messages were difficult to understand.
This patch makes them slightly better.

I think there is still room to tweak the messaging. And as we adopt
new security defaults, these messages will certainly change again.
But at least this takes us a step in the right direction.

References to "section" have been removed because if no fingerprint
is defined, "section" can never be "hostfingerprints." So just print
"hostsecurity" every time.

  abort: no repository found in '$TESTTMP' (.hg not found)!

  $ cd b1

Test updating with closed head
---------------------------------------------------------------------

  $ hg clone -U -q b1 closed-heads
  $ cd closed-heads

Test updating if at least one non-closed branch head exists

if on the closed branch head:
- update to "."
- "updated to a closed branch head ...." message is displayed
- "N other heads for ...." message is displayed

  $ hg update -q -C 3
  $ hg commit --close-branch -m 6
  $ norevtest "on closed branch head" clean 6
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  no open descendant heads on branch "default", updating to a closed head
  (committing will reopen the head, use `hg heads .` to see 1 other heads)
  parent=6

if descendant non-closed branch head exists, and it is only one branch head:
- update to it, even if its revision is less than closed one
- "N other heads for ...." message isn't displayed

  $ norevtest "non-closed 2 should be chosen" clean 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  parent=2

if all descendant branch heads are closed, but there is another branch head:
- update to the tipmost descendant head
- "updated to a closed branch head ...." message is displayed
- "N other heads for ...." message is displayed

  $ norevtest "all descendant branch heads are closed" clean 3
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  no open descendant heads on branch "default", updating to a closed head
  (committing will reopen the head, use `hg heads .` to see 1 other heads)
  parent=6

Test updating if all branch heads are closed

if on the closed branch head:
- update to "."
- "updated to a closed branch head ...." message is displayed
- "all heads of branch ...." message is displayed

  $ hg update -q -C 2
  $ hg commit --close-branch -m 7
  $ norevtest "all heads of branch default are closed" clean 6
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  no open descendant heads on branch "default", updating to a closed head
  (committing will reopen branch "default")
  parent=6

if not on the closed branch head:
- update to the tipmost descendant (closed) head
- "updated to a closed branch head ...." message is displayed
- "all heads of branch ...." message is displayed

  $ norevtest "all heads of branch default are closed" clean 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  no open descendant heads on branch "default", updating to a closed head
  (committing will reopen branch "default")
  parent=7

  $ cd ..

Test updating if "default" branch doesn't exist and no revision is
checked out (= "default" is used as current branch)

  $ hg init no-default-branch
  $ cd no-default-branch

  $ hg branch foobar
  marked working directory as branch foobar
  (branches are permanent and global, did you want a bookmark?)
  $ echo a > a
  $ hg commit -m "#0" -A
  adding a
  $ echo 1 >> a
  $ hg commit -m "#1"
  $ hg update -q 0
  $ echo 3 >> a
  $ hg commit -m "#2"
  created new head
  $ hg commit --close-branch -m "#3"

if there is at least one non-closed branch head:
- update to the tipmost branch head

  $ norevtest "non-closed 1 should be chosen" clean null
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  parent=1

if all branch heads are closed
- update to "tip"
- "updated to a closed branch head ...." message is displayed
- "all heads for branch "XXXX" are closed" message is displayed

  $ hg update -q -C 1
  $ hg commit --close-branch -m "#4"

  $ norevtest "all branches are closed" clean null
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  no open descendant heads on branch "foobar", updating to a closed head
  (committing will reopen branch "foobar")

Test obsolescence behavior
---------------------------------------------------------------------

successors should be taken in account when checking head destination

  $ cat << EOF >> $HGRCPATH

  > logtemplate={rev}:{node|short} {desc|firstline}
  > [experimental]
  > evolution=createmarkers
  > EOF

Test no-argument update to a successor of an obsoleted changeset

Test that 5 is detected as a valid destination from 3 and also accepts moving
the bookmark (issue4015)

  $ hg up --quiet --hidden 3
  $ hg up 5
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg book bm
  moving bookmark 'bm' forward from 6efa171f091b

Test that 4 is detected as the no-argument destination from 3 and also moves
the bookmark with it
  $ hg up --quiet 0          # we should be able to update to 3 directly
  $ hg up --quiet --hidden 3 # but not implemented yet.
  $ hg book -f bm
  $ hg up
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg up --quiet 0          # we should be able to update to 3 directly
  $ hg up --quiet --hidden 3 # but not implemented yet.
  $ hg up 5
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Test that 5 is not detected as a valid destination from 2
  $ hg up --quiet 0
  $ hg up --quiet 2
  $ hg up 5
  abort: uncommitted changes
  (commit or update --clean to discard changes)

Test that we don't crash when updating from a pruned changeset (i.e. has no
successors). Behavior should probably be that we update to the first
non-obsolete parent but that will be decided later.
