Like pbuf_copy, but can copy part of a pbuf to an offset in another.
pbuf_copy now uses this function internally.
Replace pbuf_take_at loop in icmp6 with pbuf_copy_partial_pbuf().
It does not make sense to return success in p == NULL or
invalid header_size_increment/header_size_decrement cases. Fix it.

This fixes the following warnings:
test_tcp.c:266:5: error: code will never be executed [-Werror,-Wunreachable-code]
pbuf_free(p);
^~~~~~~~~
- The check API 'fail' aborts the test, thus pbuf_free(p) will never be executed
pbuf.c:783:111: error: format specifies type 'unsigned short' but the argument has type 'u8_t' (aka 'unsigned char') [-Werror,-Wformat]
LWIP_DEBUGF( PBUF_DEBUG | LWIP_DBG_TRACE, ("pbuf_free: %p has ref %"U16_F", ending here.\n", (void *)p, ref));
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~
- LWIP_PBUF_REF_T is u8_t by default and doesn't match U16_F, so cast to u16_t. The cast and formatter will need to be changed
if ref is larger than 16 bits
ethernet.c:105:16: error: format specifies type 'unsigned char' but the argument has type 'unsigned int' [-Werror,-Wformat]
(unsigned)ethhdr->dest.addr[0], (unsigned)ethhdr->dest.addr[1], (unsigned)ethhdr->dest.addr[2],
~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- addr[] is type u8_t, formatter is X8_F which should be 8 bits. 'unsigned' is an int, so cast to unsighed char instead
The new functions both take size_t as increment/decrement argument instead of s16_t (which needed to be range-checked before conversion everywhere) - in most places, the direction (increment or decrement) is known anyway, so no need to encode it in a sign bit
No need to have additional if statement for PBUF_REF/PBUF_ROM.
It can be merged to the existing swtich(type) cases.

All callers pass pbuf_type to pbuf_init_alloced_pbuf(), so make it take
pbuf_type instead of u8_t.

Current code fails to allocate zero length pbuf (e.g. for PBUF_RAW PBUF_POOL),
fix it.
Fixes: eb269e61b5d3 ("First step to clean up pbuf implementation: add pbuf_alloc_reference() to allocate pbufs referencing external payload; move member initialization to common function; simplify PBUF_POOL chain allocator")
