be7ae5e36b dns: Slightly improve dns_alloc_random_port implementation
Having the variable namining ret for a pointer makes the code looks odd,
ret looks like a value variable. Rename ret to pcb.
Also simplify the code in the do {} while() loop.

13fb616bb2 Cleanup hton*/ntoh* function handling and platform abstraction
Let lwip use functions/macros prefixed by lwip_ internally to avoid naming clashes with external #includes.
Remove over-complicated #define handling in def.h
Make functions easier to override in cc.h. The following is sufficient now (no more LWIP_PLATFORM_BYTESWAP):
#define lwip_htons(x) <your_htons>
#define lwip_htonl(x) <your_htonl>

70487a43d4 Apply patch #8854: dns: Simplify #ifdef guard around dns_gethostbyname_addrtype from Axel Lin
+ Minor compile fix from me
Patch makes the code a tiny bit less lightweight (add a parameter in dns_gethostbyname which is then not used in dns_gethostbyname_addrtype) but it makes the code more readable.

The only way to exit the do-while loop is err != ERR_USE.

668d461104 dns: Fix dns_alloc_pcb for reuse an existing one case
The logic to use an already existing pcb is wrong because the idx never
advanced in the for loop, so it keep checking the same dns_pcbs[idx] for
each loop iteration. Fix it.
