sslutil: add a config knob to support TLS (default) or SSLv23 (bc) (issue4038)

Prior to this change, we default to SSLv23, which is insecure because
it allows use of SSLv2. Unfortunately, there's no constant for OpenSSL
to let us use SSLv3 or TLS - we have to pick one or the other. We
expose a knob to revert to pre-TLS SSL for the user that has an
ancient server that lacks proper TLS support.

Rebasing
D onto H - simple rebase:

  $ hg clone -q -u . a a1
  $ cd a1

  $ hg tglog
  @  7: 'H'
  |
  | o  6: 'G'
  |/|
  o |  5: 'F'
  | |
  | o  4: 'E'
  |/
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  

  $ hg rebase -s 3 -d 7
  saved backup bundle to $TESTTMP/a1/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  7: 'D'
  |
  o  6: 'H'
  |
  | o  5: 'G'
  |/|
  o |  4: 'F'
  | |
  | o  3: 'E'
  |/
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


D onto F - intermediate point:

  $ hg clone -q -u . a a2
  $ cd a2

  $ hg rebase -s 3 -d 5
  saved backup bundle to $TESTTMP/a2/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  7: 'D'
  |
  | o  6: 'H'
  |/
  | o  5: 'G'
  |/|
  o |  4: 'F'
  | |
  | o  3: 'E'
  |/
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


E onto H - skip of G:

  $ hg clone -q -u . a a3
  $ cd a3

  $ hg rebase -s 4 -d 7
  saved backup bundle to $TESTTMP/a3/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  6: 'E'
  |
  o  5: 'H'
  |
  o  4: 'F'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


F onto E - rebase of a branching point (skip G):

  $ hg clone -q -u . a a4
  $ cd a4

  $ hg rebase -s 5 -d 4
  saved backup bundle to $TESTTMP/a4/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  6: 'H'
  |
  o  5: 'F'
  |
  o  4: 'E'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


G onto H - merged revision having a parent in ancestors of target:

  $ hg clone -q -u . a a5
  $ cd a5

  $ hg rebase -s 6 -d 7
  saved backup bundle to $TESTTMP/a5/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @    7: 'G'
  |\
  | o  6: 'H'
  | |
  | o  5: 'F'
  | |
  o |  4: 'E'
  |/
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


F onto B - G maintains E as parent:

  $ hg clone -q -u . a a6
  $ cd a6

  $ hg rebase -s 5 -d 1
  saved backup bundle to $TESTTMP/a6/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  7: 'H'
  |
  | o  6: 'G'
  |/|
  o |  5: 'F'
  | |
  | o  4: 'E'
  | |
  | | o  3: 'D'
  | | |
  +---o  2: 'C'
  | |
  o |  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


These will fail (using --source):

G onto F - rebase onto an ancestor:

  $ hg clone -q -u . a a7
  $ cd a7

  $ hg rebase -s 6 -d 5
  nothing to rebase
  [1]

F onto G - rebase onto a descendant:

  $ hg rebase -s 5 -d 6
  abort: source is ancestor of destination
  [255]

G onto B - merge revision with both parents not in ancestors of target:

  $ hg rebase -s 6 -d 1
  abort: cannot use revision 6 as base, result would have 3 parents
  [255]


These will abort gracefully (using --base):

G onto G - rebase onto same changeset:

  $ hg rebase -b 6 -d 6
  nothing to rebase
  [1]

G onto F - rebase onto an ancestor:

  $ hg rebase -b 6 -d 5
  nothing to rebase
  [1]

F onto G - rebase onto a descendant:

  $ hg rebase -b 5 -d 6
  nothing to rebase
  [1]

C onto A - rebase onto an ancestor:

  $ hg rebase -d 0 -s 2
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/5fddd98957c8-backup.hg (glob)
  $ hg tglog
  @  7: 'D'
  |
  o  6: 'C'
  |
  | o  5: 'H'
  | |

  | o |  3: 'F'
  |/ /
  | o  2: 'E'

  | o  1: 'B'

  o  0: 'A'
  

Check rebasing public changeset

  $ hg pull --config phases.publish=True -q -r 6 . # update phase of 6
  $ hg rebase -d 0 -b 6
  nothing to rebase
  [1]
  $ hg rebase -d 5 -b 6
  abort: can't rebase immutable changeset e1c4361dd923
  (see hg help phases for details)
  [255]

  $ hg rebase -d 5 -b 6 --keep

Check rebasing mutable changeset
Source phase greater or equal to destination phase: new changeset get the phase of source:
  $ hg rebase -s9 -d0
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2b23e52411f4-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 9
  draft
  $ hg rebase -s9 -d1
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2cb10d0cfc6c-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 9
  draft
  $ hg phase --force --secret 9
  $ hg rebase -s9 -d0
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/c5b12b67163a-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 9

  $ hg rebase -s9 -d1
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2a0524f868ac-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 9
  secret
Source phase lower than destination phase: new changeset get the phase of destination:
  $ hg rebase -s8 -d9
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/6d4f22462821-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 'rev(9)'
  secret

  $ cd ..

Test for revset

We need a bit different graph
All destination are B

  $ hg init ah
  $ cd ah
  $ hg unbundle "$TESTDIR/bundles/rebase-revset.hg"
  adding changesets
  adding manifests
  adding file changes
  added 9 changesets with 9 changes to 9 files (+2 heads)
  (run 'hg heads' to see heads, 'hg merge' to merge)
  $ hg tglog
  o  8: 'I'

  o  7: 'H'

  o  6: 'G'

Simple case with keep:

Source on have two descendant heads but ask for one

  $ hg clone -q -u . ah ah1
  $ cd ah1
  $ hg rebase -r '2::8' -d 1
  abort: can't remove original changesets with unrebased descendants
  (use --keep to keep original changesets)
  [255]
  $ hg rebase -r '2::8' -d 1 --keep
  $ hg tglog

  o  12: 'H'

  o  11: 'G'

  o  10: 'D'

Base on have one descendant heads we ask for but common ancestor have two

  $ hg clone -q -u . ah ah2
  $ cd ah2
  $ hg rebase -r '3::8' -d 1
  abort: can't remove original changesets with unrebased descendants
  (use --keep to keep original changesets)

rebase subset

  $ hg clone -q -u . ah ah3

  $ hg rebase -r '3::7' -d 1
  abort: can't remove original changesets with unrebased descendants
  (use --keep to keep original changesets)

  | o  2: 'C'

  o |  1: 'B'

  o  0: 'A'
  

  $ cd ..

rebase subset with multiple head

  $ hg clone -q -u . ah ah4
  $ cd ah4
  $ hg rebase -r '3::(7+5)' -d 1
  abort: can't remove original changesets with unrebased descendants

More advanced tests

rebase on ancestor with revset

  $ hg clone -q -u . ah ah5
  $ cd ah5
  $ hg rebase -r '6::' -d 2
  saved backup bundle to $TESTTMP/ah5/.hg/strip-backup/3d8a618087a7-backup.hg (glob)
  $ hg tglog
  @  8: 'I'
  |
  o  7: 'H'
  |
  o  6: 'G'
  |
  | o  5: 'F'
  | |
  | o  4: 'E'
  | |
  | o  3: 'D'
  |/
  o  2: 'C'
  |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


rebase with multiple root.
We rebase E and G on B
We would expect heads are I, F if it was supported

  $ hg clone -q -u . ah ah6
  $ cd ah6
  $ hg rebase -r '(4+6)::' -d 1
  saved backup bundle to $TESTTMP/ah6/.hg/strip-backup/3d8a618087a7-backup.hg (glob)
  $ hg tglog
  @  8: 'I'
  |
  o  7: 'H'
  |
  o  6: 'G'
  |
  | o  5: 'F'
  | |
  | o  4: 'E'
  |/
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  o |  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..

More complex rebase with multiple roots
each root have a different common ancestor with the destination and this is a detach

(setup)

  $ hg clone -q -u . a a8
  $ cd a8
  $ echo I > I
  $ hg add I
  $ hg commit -m I
  $ hg up 4
  1 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ echo I > J
  $ hg add J
  $ hg commit -m J
  created new head
  $ echo I > K
  $ hg add K
  $ hg commit -m K
  $ hg tglog
  @  10: 'K'
  |
  o  9: 'J'
  |
  | o  8: 'I'
  | |
  | o  7: 'H'
  | |

  | o  3: 'D'

  | o  2: 'C'
