smbios: Make multiple -smbios type= accumulate sanely

Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with
value VAL to fw_cfg for each unique NAME. If NAME occurs multiple
times, the last one's VAL is used (before the QemuOpts conversion, the...

smbios: Convert to QemuOpts

So that it can be set in config file for -readconfig.

This tightens parsing of -smbios, and makes it more consistent with
other options: unknown parameters are rejected, numbers with trailing
junk are rejected, when a parameter is given multiple times, last...

smbios: Normalize smbios_entry_add()'s error handling to exit(1)

It exits on all error conditions but one, where it returns -1.
Normalize, and return void.

e1000: add interrupt mitigation support

This patch partially implements the e1000 interrupt mitigation mechanisms.
Using a single QEMUTimer, it emulates the ITR register (which is the newer
mitigation register, recommended by Intel) and approximately emulates...

pc: reduce duplication, fix PIIX descriptions

We have a lot of code duplication between machine types,
this increases with each new machine type
and each new field.

This has already introduced a minor bug: description
for pc-1.3 says "Standard PC" while description for...

pc: fix regression for 64 bit PCI memory

commit 398489018183d613306ab022653552247d93919f
pc: limit 64 bit hole to 2G by default
introduced a way for management to control
the window allocated to the 64 bit PCI hole.

This is useful, but existing management tools do not know how to set...

pc: limit 64 bit hole to 2G by default

It turns out that some 32 bit windows guests crash
if 64 bit PCI hole size is >2G.
Limit it to 2G for piix and q35 by default.
User may override default 64-bit PCI hole size by
using "pci-hole64-size" property.

Examples:...

target-i386: Disable PMU CPUID leaf by default

Bug description: QEMU currently gets all bits from GET_SUPPORTED_CPUID
for CPUID leaf 0xA and passes them directly to the guest. This makes
the guest ABI depend on host kernel and host CPU capabilities, and
breaks live migration if we migrate between hosts with different...
