#7321: Make hard-coded activity excerpt length a filterable function

 Currently there are 2 places:

 {{{
 // bp-activity/bp-activity-filters.php
 $excerpt_length = apply_filters( 'bp_activity_excerpt_length', 358 );
 // bp-activity/bp-activity-template.php
 $latest_update = apply_filters( 'bp_get_activity_latest_update_excerpt',
 trim( strip_tags( bp_create_excerpt( $update['content'], 358 ) ) ),
 $user_id );
 }}}

 I propose to create `bp_activity_get_excerpt_length()`, with
 `bp_activity_excerpt_length` filter in it.

 {{{
 function bp_activity_get_excerpt_length() {
     return apply_filters( 'bp_activity_excerpt_length', 358 );
 }
 }}}

 And the 1st usage will be changed to a direct function usage without
 filters, and the second to this:

 {{{
 $latest_update = apply_filters(
     'bp_get_activity_latest_update_excerpt',
     trim( strip_tags( bp_create_excerpt( $update['content'],
 bp_activity_get_excerpt_length() ) ) ),
     $user_id
 );
 }}}
