This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
...
This makes the user interface a little hostile. People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header). A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length. Instead, we define the packet buffer size then derive the MTU.
The MTU is not common currency in networking. On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP). Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes. So we should be all good and without the recurring 14 byte error in MTU's and MSS's.
Squashed commit of the following:
Trivial update to fix some spacing issues.
net/: Rename several macros containing _MTU to _PKTSIZE.
net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU. These are not the MTU which does not include the size of the link layer header. These are the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU. These are not the MTU which does not include the size of the link layer header. These are the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE. This is not the MTU which does not include the size of the link layer header. This is the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename the file d_mtu in the network driver structure to d_pktsize. That value saved there is not the MTU. The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header. The MTU does not include the link layer header.

Build system: Remove fixed lib/ subdirectory and its content. Replace with new directory called staging/ that is created dynamically when building and removed when 'make clean' is done. This both improves the name and eliminates a garbage directory from the repository.

Per OpenGroup.org, syslog -- and, hence, nonstandard vsyslog, and debug wrappers -- does not return a value. Rename _vsyslog to nx_vsyslog. Use internal nx_vsyslog in the few cases where a return value is required.

The existence of the network driver ioctl() method should depend on CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL. The former enables the method, the later enables a subset of possible driver IOCTLs. This change should be basically a no-operation. The affected ioctl methods only support those subset of driver IOCTLs selected by CONFIG_NETDEV_PHY_IOCTL and the network logic will tolerate a nul ioctl method.

up_timer_initialize() is named incorrectly. The prefix should be the architecture name, not up_ since it is private to the architecture. up_timerisr() is similarly misnamed and should also be private since it is used only with the xyz_timerisr.c files. Also updat TODO list.

This change provides an option to add /dev/urandom to all architectures. The pseudo-random algorithm I choose strikes an arguably-good balance between being "random" and small/fast enough for 8/16 bit MCUs. It’s the well-documented xorshift128 algorithm. It has an internal state of 128 bits that can be [re-]seeded with a write.
