Deprecated functions for 1.7

[r-a-y]

Master ticket for functions we should deprecate for 1.7.

Was briefly looking through the codebase last night and came across these functions:

• xprofile_get_profile()
• bp_get_profile_header()
• bp_exists()
• bp_get_plugin_sidebar()

[jkudish]

deprecate the functions

[boonebgorges]

(In [6415]) Deprecates some functions no longer used in 1.7:

• xprofile_get_profile()
• bp_get_profile_header()
• bp_exists()
• bp_get_plugin_sidebar()

Also adds the logic to bp-loader for actually loading 1.7 deprecated functions

See #4592

Props r-a-y, jkudish

Oh yeah, forgot to include the file :)

[jkudish]

adjust the @deprecated Since paramater in the 1.7 deprecated functions file

Props for the patch, but r-a-y already committed a fix for this in r6418 :)

Great!
