[Minios-devel] [UNIKRAFT/LWIP PATCH v2] Provide gethostbyname and gethostbyname_r

[Mihai Pogonaru <pogonarumihai@xxxxxxxxx>]

Define gethostbyname and gethostbyname_r as their LWIP counterparts.
The defines are in place in origin/netdb.h, but they are protected by
LWIP_COMPAT_SOCKETS, which for us is defined as 0 since we provide
wrappers for most of socket.h functions.
