tests: add test showing broken extension loading in case of share-safe
When we are using share-safe and loading source repository config, we are still
not loading the extensions which are enabled in the source repository.
This patch demonstrates the bug. Meanwhile it also shows how unreliable `hg
debugextensions` is.

Create a shared repo and check the requirements are shared and read correctly
$ hg share source shared1
updating working directory
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd shared1

$ echo c > c
$ hg ci -Aqm "added c"
Check that config of the source repository is also loaded
$ hg showconfig ui.curses
[1]
$ echo "[ui]" >> ../source/.hg/hgrc
$ echo "curses=true" >> ../source/.hg/hgrc
$ hg showconfig ui.curses
true
Test that extensions of source repository are also loaded
$ hg debugextensions
share
$ hg extdiff -p echo
hg: unknown command 'extdiff'
'extdiff' is provided by the following extension:
extdiff command to allow external programs to compare revisions
(use 'hg help extensions' for information on enabling extensions)
[255]
$ echo "[extensions]" >> ../source/.hg/hgrc
$ echo "extdiff=" >> ../source/.hg/hgrc
$ hg debugextensions -R ../source
extdiff
share
$ hg extdiff -R ../source -p echo
BROKEN: the command below does not work but debugextensions says that extension
is loaded
$ hg debugextensions
extdiff
share
BROKEN: extdiff command should work here
$ hg extdiff -p echo
hg: unknown command 'extdiff'
'extdiff' is provided by the following extension:
extdiff command to allow external programs to compare revisions
(use 'hg help extensions' for information on enabling extensions)
[255]
However, local .hg/hgrc should override the config set by share source
$ echo "[ui]" >> .hg/hgrc
$ echo "curses=false" >> .hg/hgrc
$ hg showconfig ui.curses
false
$ HGEDITOR=cat hg config --shared
[ui]
curses=true
[extensions]
extdiff=
$ HGEDITOR=cat hg config --local
[ui]
curses=false
Testing that hooks set in source repository also runs in shared repo

Test that if share source config is untrusted, we dont read it
$ cd ../shared1

Update the source repository format and check that shared repo works
$ cd ../source
Disable zstd related tests because its not present on pure version
