The file is only including error.h and qerror.h.  Prefer explicit

Move public headers to include/net, and leave private headers in net/.
Put the virtio headers in include/net/tap.h, removing the multiple copies
that existed.  Leave include/net/tap.h as the interface for NICs, and
net/tap_int.h as the interface for OS-specific parts of the tap backend.

Touching char/char.h basically causes the whole of QEMU to
be rebuilt.  Avoid this, it is usually unnecessary.
Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

Various header files rely on qemu-char.h including qemu-config.h or
main-loop.h, but they really do not need qemu-char.h at all (particularly
interesting is the case of the block layer!).  Clean this up, and also
add missing inclusions of qemu-char.h itself.

With MMU option xtensa architecture has two TLBs: ITLB and DTLB. ITLB is
only used for code access, DTLB is only for data. However TLB entries in
both TLBs have attribute field controlling write and exec access. These
bits need to be properly masked off depending on TLB type before being
used as tlb_set_page prot argument. Otherwise the following happens:

(1) ITLB entry for some PFN gets invalidated
(2) DTLB entry for the same PFN gets updated, attributes allow code
    execution
(3) code at the page with that PFN is executed (possible due to step 2),
    entry for the TB is written into the jump cache
(4) QEMU TLB entry for the PFN gets replaced with an entry for some
    other PFN
(5) code in the TB from step 3 is executed (possible due to jump cache)
    and it accesses data, for which there's no DTLB entry, causing DTLB
    miss exception
(6) re-translation of the TB from step 5 is attempted, but there's no
    QEMU TLB entry nor xtensa ITLB entry for that PFN, which causes ITLB
    miss exception at the TB start address
(7) ITLB miss exception is handled by the guest, but execution is
    resumed from the beginning of the faulting TB (the point where ITLB
    miss occured), not from the point where DTLB miss occured, which is
    wrong.

With that fix the above scenario causes ITLB miss exception (that used
to be step 7) at step 3, right at the beginning of the TB.
