hgweb: construct static URL like hgweb does

hgwebdir has a bit of code for constructing URLs. This reinvents wheels
from our parsedrequest instance. And sometimes the behavior varies
from what hgweb does. We'll want to converge that behavior.

This commit changes hgwebdir so its staticurl template keyword
is constructed the same way as hgweb's. There's probably room
to factor this into a shared function. But let's solve the
problem of divergence first.

Rebase a simple DAG:
  $ hg init repo1
  $ cd repo1
  $ hg debugdrawdag <<'EOS'
  > c b
  > |/
  > d
  > |
  > a
  > EOS
  $ hg up -C a
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg tglog
  o  3: 814f6bd05178 'c'
  |
  | o  2: db0e82a16a62 'b'
  |/
  o  1: 02952614a83d 'd'
  |
  @  0: b173517d0057 'a'
  
  $ hg cat -r 3 c
  c (no-eol)
  $ hg cat -r 2 b
  b (no-eol)
  $ hg rebase --debug -r b -d c | grep rebasing
  rebasing in-memory
  rebasing 2:db0e82a16a62 "b" (b)
  $ hg tglog
  o  3: ca58782ad1e4 'b'
  |
  o  2: 814f6bd05178 'c'
  |
  o  1: 02952614a83d 'd'
  |
  @  0: b173517d0057 'a'
  
  $ hg cat -r 3 b
  b (no-eol)
  $ hg cat -r 2 c
  c (no-eol)

Case 2:
  $ hg init repo2
  $ cd repo2
  $ hg debugdrawdag <<'EOS'
  > c b
  > |/
  > d
  > |
  > a
  > EOS

Add a symlink and executable file:
  $ hg up -C c
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ ln -s somefile e
  $ echo f > f
  $ chmod +x f
  $ hg add e f
  $ hg amend -q
  $ hg up -Cq a

Write files to the working copy, and ensure they're still there after the rebase
  $ echo "abc" > a
  $ ln -s def b
  $ echo "ghi" > c
  $ echo "jkl" > d
  $ echo "mno" > e
  $ hg tglog
  o  3: f56b71190a8f 'c'

  | o  2: db0e82a16a62 'b'

  o  1: 02952614a83d 'd'

  @  0: b173517d0057 'a'
  
  $ hg cat -r 3 c
  c (no-eol)
  $ hg cat -r 2 b
  b (no-eol)
  $ hg cat -r 3 e
  somefile (no-eol)
  $ hg rebase --debug -s b -d a | grep rebasing
  rebasing in-memory
  rebasing 2:db0e82a16a62 "b" (b)
  $ hg tglog
  o  3: fc055c3b4d33 'b'
  |
  | o  2: f56b71190a8f 'c'
  | |
  | o  1: 02952614a83d 'd'
  |/
  @  0: b173517d0057 'a'
  
  $ hg cat -r 2 c
  c (no-eol)
  $ hg cat -r 3 b
  b (no-eol)
  $ hg rebase --debug -s 1 -d 3 | grep rebasing
  rebasing in-memory
  rebasing 1:02952614a83d "d" (d)
  rebasing 2:f56b71190a8f "c"
  $ hg tglog
  o  3: 753feb6fd12a 'c'

  o  2: 09c044d2cb43 'd'

Ensure working copy files are still there:
  $ cat a
  abc
  $ readlink.py b
  b -> def
  $ cat e
  mno

Ensure symlink and executable files were rebased properly:
  $ hg up -Cq 3
  $ readlink.py e
  e -> somefile
  $ ls -l f | cut -c -10
  -rwxr-xr-x

Rebase the working copy parent, which should default to an on-disk merge even if
we requested in-memory.
  $ hg up -C 3
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg rebase -r 3 -d 0 --debug | grep rebasing
  rebasing on disk
  rebasing 3:753feb6fd12a "c" (tip)
  $ hg tglog
