api: config: Renamed ODP_CONFIG_PACKET_BUF_LEN_MIN
Renamed ODP_CONFIG_PACKET_BUF_LEN_MIN to ODP_CONFIG_PACKET_SEG_LEN_MIN.
The packet pool parameter pkt.seg_len is rounded up into this value.
Added ODP_CONFIG_PACKET_SEG_LEN_MAX to define the maximum segment
length supported by the implementation. This is the maximum valid
value for pkt.seg_len.
If ODP_CONFIG_PACKET_SEG_LEN_MIN equals _SEG_LEN_MAX, the
implementation supports only one segment length value.
