Okay, works fine, except when I try to have a page served
by a secure virtual server under Stronghold. Normally,
things work fine, but a <? tag anywhere in a document
will cause Stronghold to segfault nicely when my request
is going to an SSL-enrypted virtual server.

Here's a stack trace. (compiled with stronghold debugging
off, php debugging on. Let me know if you need more)

Fixed.  Stronghold has NULL elements on the
apache environment table, and hash_environment()
was trying to copy a string from there.

Log: - Revamp of the decoding portion of html.c.
- Dramatic improvements on the performance of html_entity_decode and htmlspecialchars_decode, as the
  string is now traversed only once. Speedups of 20 to 25 times with Windows release builds and a
  ~250 characters string (for 2nd and subsequent calls).
- Consistent behavior on html_entity_decode. For instance, the entity in &quot;&amp;&amp;lt;&quot; would be decoded,
  but not &quot;&amp;&amp;#233;&quot;. Not anymore. The code path for &quot;basic&quot; and non-basic entities is now mostly
- Code of html_entity_decode and htmlspecialchars_decode is now shared.
- [DOC] More consistent behavior of htmlspecialchars_decode. Instead of translating only &amp;lt;, &amp;gt;,
  &amp;amp;, &amp;quot;, &amp;#039; and &amp;#39;, now e.g. &amp;#34;, &amp;apos;, &amp;#0039;, &amp;#x27;, etc. are also decoded.
- [DOC] Previous translation of unicode code points in numerical entities was seriously broken. When
  the code points for some character were not the same in unicode and the target encoding, the
  behavior could be an erroneous translation (e.g. 0x80-0xA0 in win-1252) or no translation at all.
  Added unicode translation tables for all single-byte encodings. Entities are not translated for
  multi-byte entities, except for ASCII characters whose code points are shared. We could add
  the huge translation tables (several thousand elements) for those encodings in the future.
- Fixed numerical entities that after # had text accepted by strcol being accepted.
- Much more commented and well-structured code...
- Tests for get_html_translation_table()) are broken. I stared fixing the tests, but then I realized
  it was completely helpless because get_html_translation_table() is broken by not handling
  multi-byte characters correctly.

Automatic comment from SVN on behalf of cataphract
Log: - Added a 3rd parameter to get_html_translation_table. It now takes a charset
  hint, like htmlentities et al.
- Fixed bug #49407 (get_html_translation_table doesn't handle UTF-8).
- Fixed bug #25927 (get_html_translation_table calls the ' &amp;#39; instead of
- Fixed tests for get_html_translation_table and unified the Windows and
  non-Windows versions of the tests.
