This commit moves the warn_if_private_stream_is_linked,
needs_subscribe_warning, and warn_if_mentioning_unsubscribed_user
to compose_validate.js from compose.js.
These warning functions are very naturally part of the compose box
validation system, though they're a bit different in being called from
the typeahead codebase.
Part of splitting compose.js into more natural modules.
We are doing this to avoid annoying behavior, when
"enter sends" is enabled, and the user accidentally hits
"Enter" and has to deal with the error message.
Fixes#19182
We improved it in the following ways:
* Show the error message with the maximum character
limit.
* Disable the send button.
* When the user tries to send the message via hotkeys
i.e, When "Press enter to send" is enabled or the user
uses "Shift" + "Enter" shortcut, Flash the red border
around the compose box.
Also renamed `check_and_set_overflow_text` to
`check_overflow_text` for better clarity.
Fix a bug where the compose box cut the message without warning the user
the message pasted was longer than the allowed. It was fixed by stopping
cutting the message off and showing an indicator whenever the limit exceeds
and removing the indicator as soon as message gets less than that.
The cut off for showing the indicator is set as 90% of the limit.
Fixes#15909

This commit first moves the compose.validate() function out
with the functions that are needed by it. Then one by one
checked for which function is now not needed in compose.js.
This moves all validation related functions out of "compose.js"
to "compose_validate.js".
Splitting compose announce variables out of compose.js.
This commit moves the "user_acknowledged_all_everyone" and
"user_acknowledged_announce" out of compose.js to reduce
cyclic dependency of compose_validate on compose.js.
Moving wildcard mentions to compose_validate.
The wildcard mention settings are mostly used while validating.
Also to reduce the cyclic dependence of compose in
compose_validate, the related wildcard mentions are moved out to
compose_vaidate.js.
This also converts reset_acknowledged functions to set values
by passing values.
