dispatch: load shared source repository config in share-safe mode
It seems to me now that there are two steps when config is loaded:
1) on dispatch
2) repository object creation
Recent patches added functionality that there can be shares in share-safe mode
where config of the source repository is shared with the the shares. However we
missed adding logic to read the source config on dispatch. This leads to
extensions not being loaded on dispatch and hence extensions command not being
recognized.
This patch fixes it by reading the shared source config on dispatch.

Utility for inspecting files in various ways.
This tool is like the collection of tools found in a unix environment but are
cross platform and stable and suitable for our needs in the test suite.
This can be used instead of tools like:
[
dd
find
head
hexdump
ls
md5sum
readlink
sha1sum
stat
tail
test
readlink.py
