Reorganize option rom (+linux kernel) loading.
This patch adds infrastructure to maintain memory regions which must berestored on reset. That includes roms (vga bios and option roms on pc),but is also used when loading linux kernels directly. Features:...
Improve error reporting on file access
By making the error reporting include strerror(errno), it gives the usera bit more indication as to why qemu failed. This is particularlyimportant for people running qemu as a non root user.

Fix pci_add nic not to exit on bad model

Change pci_nic_init() not to treat "?" specially, and to return NULL...
serial: convert isa to qdev
Everything using standard isa I/O ports and IRQ windup is considerdbeing an actual isa device. That are all serial_init() users exceptmips_mipssim() which seems to have a non-standard IRQ windup.
baud rate is fixed at 115200 now as no caller passed in something else....

Also hard-code isa interrupts which can't be configured anyway.
isapc: pick a more sane default cpu for such old hardware.
qdev: drop iobase properties from isa bus
