typo fixes - https://github.com/vlajos/misspell_fixer

These files contained a bit live code: ext/soap/php_soap.h, ext/soap/soap.c

(I hope I didn't break any tests, but I couldn't run them... My compiler environment isn't really working...)

To be honest I have no idea...
Anyway feel free to skip these files or let me know if it is easier if I remove them from the PR.
