repair: use context manager for lock management

If repo.lock() raised inside of the try block, 'tr' would have been None in the
finally block where it tries to release().  Modernize the syntax instead of just
winching the lock out of the try block.

I found several other instances of acquiring the lock inside of the 'try', but
those finally blocks handle None references.  I also started switching some
trivial try/finally blocks to context managers, but didn't get them all because
indenting over 3x for lock, wlock and transaction would have spilled over 80
characters.  That got me wondering if there should be a repo.rwlock(), to handle
locking and unlocking in the proper order.

It also looks like py27 supports supports multiple context managers for a single
'with' statement.  Should I hold off on the rest until py26 is dropped?

  $ hg init a

  $ echo a > a/a
  $ hg --cwd a ci -Ama
  adding a

  $ hg clone a c
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg clone a b
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ echo b >> b/a
  $ hg --cwd b ci -mb

Push should provide a hint when both 'default' and 'default-push' not set:
  $ cd c
  $ hg push --config paths.default=
  abort: default repository not configured!
  (see 'hg help config.paths')
  [255]

  $ cd ..

Push should push to 'default' when 'default-push' not set:

  $ hg --cwd b push
  pushing to $TESTTMP/a (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

Push should push to 'default-push' when set:

  $ echo '[paths]' >> b/.hg/hgrc
  $ echo 'default-push = ../c' >> b/.hg/hgrc
  $ hg --cwd b push
  pushing to $TESTTMP/c (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

But push should push to 'default' if explicitly specified (issue5000):

  $ hg --cwd b push default
  pushing to $TESTTMP/a (glob)
  searching for changes
  no changes found
  [1]

Push should push to 'default-push' when 'default' is not set

  $ hg -q clone a push-default-only
  $ cd push-default-only
  $ rm .hg/hgrc

  $ touch foo
  $ hg -q commit -A -m 'add foo'
  $ hg --config paths.default-push=../a push
  pushing to $TESTTMP/a (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

  $ cd ..

Pushing to a path that isn't defined should not fall back to default

  $ hg --cwd b push doesnotexist
  abort: repository doesnotexist does not exist!
  [255]

:pushurl is used when defined

  $ hg -q clone a pushurlsource
  $ hg -q clone a pushurldest
  $ cd pushurlsource

Windows needs a leading slash to make a URL that passes all of the checks
  $ WD=`pwd`
#if windows
  $ WD="/$WD"
#endif
  $ cat > .hg/hgrc << EOF
  > [paths]
  > default = https://example.com/not/relevant
  > default:pushurl = file://$WD/../pushurldest
  > EOF

  $ touch pushurl
  $ hg -q commit -A -m 'add pushurl'
  $ hg push
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

:pushrev is used when no -r is passed

  $ cat >> .hg/hgrc << EOF
  > default:pushrev = .
  > EOF
  $ hg -q up -r 0
  $ echo head1 > foo
  $ hg -q commit -A -m head1
  $ hg -q up -r 0
  $ echo head2 > foo
  $ hg -q commit -A -m head2
  $ hg push -f
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)

  $ hg --config 'paths.default:pushrev=draft()' push -f
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)

Invalid :pushrev raises appropriately

  $ hg --config 'paths.default:pushrev=notdefined()' push
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  hg: parse error: unknown identifier: notdefined
  [255]

  $ hg --config 'paths.default:pushrev=(' push
  pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
  hg: parse error at 1: not a prefix: end
  [255]

  $ cd ..
