    _______________________________________________________

Details:

when custom lwippools.h files are used, sizeof() often can't be used because
#include lines into own libraries (which would declare what is to be sizeof'd)
would go in the middle of enum declarations and such.

that can be easily circumvented by including lwip/memp_std.h "blank" once,
which causes all external includes to be resolved; when it's later used with
LWIP_MEMPOOL defined, the include guards of the external headers get
triggered, and nothing problematic gets included.

a patch with explanation is attached.
