T15691: PHP 8.1 "strlen(null)" exception creating Maniphest task when custom select field configured

Commits

rP8e09dbfee343: Fix PHP 8.1 exception creating task when custom select field configured

Summary

strlen() was used in Phabricator to check if a generic value is a non-empty string.
This behavior is deprecated since PHP 8.1. Phorge adopts phutil_nonempty_string() as a replacement.

Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If phutil_nonempty_string() throws an exception in your
instance, report it to Phorge to evaluate and fix that specific corner case.

EXCEPTION: (RuntimeException) strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [<arcanist>/src/error/PhutilErrorHandler.php:261]
  #0 <#2> PhutilErrorHandler::handleError(integer, string, string, integer) called at [<phorge>/src/infrastructure/customfield/standard/PhabricatorStandardCustomFieldSelect.php:14]

Closes T15691

Test Plan

After configuring a custom select field, try to create a task via a Maniphest form using that custom field.

14	Can value be non-string like integer? Might be safer to null-check && strlen

I assumed that $this->newStringIndex($value) in the next line implies a string here but let's play safe, indeed.

This works as long as getFieldValue() never returns an object (that has a toString, that may be empty)

But, assuming that line 76 never exploded (so, object never met), this is OK to me

76–78	Interesting piece

Does anyone dare to accept the last revision? :)

Same comment about keeping strlen. Up to you if you want to switch before landing.

Use strlen() instead of empty string check
