function name_clean_name_component in Name Field 7

Checks that the name matches a reasonable format before saving it to the database.

The valid list so far is:

xxx > Xxx d'xxx > D'Xxx l'xxx > L'Xxx m'xxx > M'Xxx o'xxx > O'Xxx de|del|des|di|du|la|le|van|von xxx > De Xxx de la xxx > De la Xxx van|von de|den|der xxx > Van Xxx st|st.|staint xxx > Staint Xxx van der xxx > Van der Xxx mc|mac xxx > McXxx

Ignored list includes:

xxx xxx etc

Configurable options:

xxx-xxx x

Note that this is an API change from Name Field 7.x-1.4 to 7.x-1.5 that was required after implementing theme_name_component(). The previous version of this function was name_process_name_component().
