Details:

HTTP header names must be matched in a case-insensitive way as per RFC2616.
This bug caused all POST requests whose headers that don't use the
conventional
Pascal+kebab case to fail. The popular axios libary uses lowercase header
names
for example.

A new function `lwip_strncasestr` was implemented in src/core/def.c that's a
case-insensitive variant of `lwip_strnstr`.
