(Similar to bug #34757).

When input string length = 1, iconv_substr() produces "Unknown error (0)" and returns FALSE.

Reproduce code:
$s = 'x';
$s = iconv_substr($s, 0, 1, 'UTF-8');


Expected result:
string(1) "x"

Actual result:

and Notice: iconv_substr() [function.iconv-substr.html]: Unknown error (0) in ...

the patch removes a strange 'switch (errno)' that I don't really know why it was there and adds a check for _php_iconv_appendl()

The switch clause is needed so that illegal multibyte occurrences would be detected per specification. I'm going to look into this one.
