This commit expands all uses of the INLINE macro and drop it.
The reason for this is to avoid clashes with external libraries with
bad name conventions and also because renaming keywords is not a good
practice.
PS: I'm fine with this change to be licensed under softfloat-2a or
softfloat-2b.

The current code is broken: it does surprise removal which crashes guests.
Reimplemented the steps:
- Hotplug triggers both 'present detect change' and
'attention button pressed'.
- Hotunplug starts by triggering 'attention button pressed',
then waits for the OS to power off the device and only
then detaches it.

pc-q35-1.4 was incorrectly using PC_COMPAT_1_4 instead of
PC_Q35_COMPAT_1_4.
The only side-effect was that the hpet compat property (inherited from
PC_Q35_COMPAT_1_7) was missing.
Without this patch, pc-q35-1.4 inicorrectly initializes hpet-intcap to
0xff0104 (behavior introduced in QEMU 2.0, by commit
7a10ef51c2).

Commit c76bf6bb8f ("Add chardev API
qemu_chr_fe_get_msgfds") extended the get_msgfds API from one to
multiple file descriptors. It forgot to close unused file descriptors
before freeing the file descriptor array.
This patch prevents a file descriptor leak if the tcp_get_msgfds()
callers requests fewer file descriptors than are available.

Commit c76bf6bb8f ("Add chardev API
qemu_chr_fe_get_msgfds") broke qemu_chr_fe_get_msgfd() because it
changed the return value.
Callers expect -1 if no fd is available. The commit changed the return
value to 0 (which is a valid file descriptor number) so callers always
detected a file descriptor even if none was available.

Using mii-tool (on F20-live), the following output is produced:
SIOCGMIIREG on ens3 failed: Input/output error
ens3: no autonegotiation, 1000baseT-FD flow-control, link ok
The first line (SIOCGMIIREG error) is due to mii-tool's inability
to read the PHY auto-negotiation expansion register.
On the second line, "no autonegotiation" is wrong, and caused by
the absence of a flag in the link partner ability register which
would indicate that our link partner has acked us. This flag is
listed as "reserved" in the Intel e1000 manual, but mii-tool uses
it as LPA_LPACK from /usr/include/linux/mii.h.
This patch adds read access to PHY_AUTONEG_EXP and defines the
link partner ack flag, allowing mii-tool to generate output as
normally expected:
ens3: negotiated 1000baseT-FD flow-control, link ok

This patch emulates auto-negotiation when the network link status
is modified externally (i.e. via "set_link <id> off/on").
Also, a couple of cleanup items:
- unset PHY status reg. AUTONEG_COMPLETE during link_down()
- set PHY status reg. AUTONEG_COMPLETE during autoneg_timer() only
if we actually brought the link up.
- group all checks for "can we, and should we autonegotiate?"
together for more clarity.
