configure: Enable TPM by default, add --disable-tpm

I don't see why tpm is disabled by default: it doesn't have any
external dependencies, or change default behavior. Leaving it disabled
is just going to cause it to bit rot.

Enable it by default, and add a --disable-tpm option.

target-ppc: Fix compiler warning

gcc reports a warning which is usually wrong:

target-ppc/dfp_helper.c: In function ‘dfp_get_digit’:
target-ppc/dfp_helper.c:417:1: warning:
 control reaches end of non-void function [-Wreturn-type]

The compiler shows the warning if assert is not marked with the noreturn
attribute or if the code is compiled with -DNDEBUG.

Using g_assert_not_reached better documents the intention and does not
have these problems.

Increase maximum number of session of the internal TFTP server.

Grub fails to boot from internal TFTP server when loading more than
3 initrd files.

Grub first opens a session to the TFTP server for every initrd file and
retrieves only the file size for all.
Then it wants to download the content using the old sessions which are
already expired.

Increasing the maximum number of session of the internal TFTP
server avoids this issue.

The error message reads as following:
error: timeout reading
`/boot/ISO.ROOT/BOOTMGR'.

Add support for the arm breakpoint syscall

OABI arm used a software interrupt(0xef9f0001) for breakpoints.
Since 2005 gdb has used the break instruction(0xe7f001f0) for EABI.
Apparently Steel Bank Common Lisp still uses the swi instruction.

This is the kernel implementation:

target-i386: kvm: Don't enable MONITOR by default on any CPU model

KVM never supported the MONITOR flag so it doesn't make sense to have it
enabled by default when KVM is enabled.

The rationale here is similar to the cases where it makes sense to have
a feature enabled by default on all CPU models when on KVM mode (e.g.
x2apic). In this case we are having a feature disabled by default for
the same reasons.

In this case we don't need machine-type compat code because it is
currently impossible to run a KVM VM with the MONITOR flag set.
