Recent addition of notmuch-message-mode introduced several problems:
1. When message-setup-hook is used to set buffer local variables,
these settings are not effective, because all buffer local
variables are immediately erased by notmuch-message-mode
initialization.
2. message-mode-hook gets invoked twice - first when message-mail
invokes message-mode and second when notmuch-mua-mail invokes
notmuch-message-mode.
This commit fixes these problems by replacing a call to message-mail
with notmuch-specific code that is (hopefully) equivalent to
message-mail functionality before introduction of
notmuch-message-mode.
We first initialize notmuch-message-mode with
notmuch-mua-pop-to-buffer, which is a modified version of
message-pop-to-buffer and then call message-setup-1, which is the only
functionality of message-mail that is needed for notmuch.
