import-checker: use testparseutil.embedded() to centralize detection logic
This patch fixes issues of embedded() in import-checker.py below, too.
- overlook (or mis-detect) the end of inline script in doctest style
- overlook inline script in doctest style at the end of file
(and ignore invalid un-closed heredoc at the end of file, too)
- overlook code fragment in styles below
- "python <<EOF" (heredoc should be "cat > file <<EOF" style)
- "cat > foobar.py << ANYLIMIT" (limit mark should be "EOF")
- "cat << EOF > foobar.py" (filename should be placed before limit mark)
- "cat >> foobar.py << EOF" (appending is ignored)
#require serve repobundlerepo
$ hg init server
$ cd server
$ cat >> .hg/hgrc << EOF

$ echo 1 > foo
$ hg commit -A -m 'first'
adding foo
$ echo 2 > bar

Produce a bundle to use
$ hg strip -r 1
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
saved backup bundle to $TESTTMP/server/.hg/strip-backup/ed602e697e0f-cc9fff6a-backup.hg
Serve from a bundle file
$ hg serve -R .hg/strip-backup/ed602e697e0f-cc9fff6a-backup.hg -d -p $HGPORT --pid-file=hg.pid
$ cat hg.pid >> $DAEMON_PIDS
Ensure we're serving from the bundle
$ (get-with-headers.py localhost:$HGPORT 'file/tip/?style=raw')
200 Script output follows
-rw-r--r-- 2 bar
-rw-r--r-- 2 foo
