Using BTM_IO_CAP_NONE currently causes compilation to fail since
bta_dm_sp_cback ends up unused out a previous #ifdef that only kicks
in if BTM_IO_CAP_NONE is not set. Plugging the entire function into
a #ifdef so consistency is maintained and the framework can compile.

Some devices claim they can handle large MTU and large SBC bitpool.
However, they are struggling and eventually over time they
start delaying the "Rcvd Number of Completed Packets" reports.
Now we always limit the payload MTU to MAX_2MBPS_AVDTP_MTU(663) -
with the overhead of (4 bytes L2CAP Header + 12 bytes AVDTP Header)
such packet can fit within 2-DH5 payload size of 679 bytes.

Some Sink devices might advertise AAC zero bitrate or a very small
value (e.g., 24576). Ignore values that are below a threshold
(currently set to 64000), because those seem invalid.
For such devices, the actual streaming bitrate will be computed
based on the MTU.

Some assigns snuck into our conditionals, making the code harder to
read / follow.

Also remove some unnecessary null checks after osi_malloc that are
nearby.

Use Case: DUT unable to pair with Xbox HID device

Steps:
1. Turn on BT
2. Start Inquiry
3. Pair with device with three extended feature pages

Failure: Unable to pair with HID device

Root Cause: DUT not responding for btm_read_remote_ext_features_complete
as we are not supporting three extended pages. So Security procedure also
not getting started.

Fix: Increase max remote ext feature pages to three from
2 as some latest remotes supporting three extended pages.
As per spec we can support 255 extended pages.

Test: Pair with device with three extended feature pages

In build/BUILD.gn we set EXPORT_SYMBOL value, and it's used across the
whole stack. However, third party libraries require this value to be
cleared - otherwise the symbols are not exported properly.

Make btsnd_hcic_ble_rand accept base::Callback instead of function
pointer. This will result in great code simplifications in further
patches.

Reverting due to the fact that this causes many HID issues with fugu. 
The general problem seems to be that this patch requires kernel 3.18 
while fugu is currently on 3.10. Will investigate further later but 
reverting for now to fix fugu.

This reverts commit 6fbe4548.

This change is needed, because there are Sink devices that
expect a fixed latmBufferFullness value.

Use AACENC_PEAK_BITRATE to limit the maximum bitrate as limited by
the MTU, and use AACENC_BITRATE to set the encoder bitrate.

Previously, both were set to the same value. That was disabling
the AAC bitreservoir, and eventually affecting the audio quality.

Right now, hci_close() is getting stuck on stopping the reader thread.
In order to fix that, we must have a way to exit the blocking read when
shutting down the stack.

If the Audio-to-Bluetooth HAL reopens a connection on the Data or
Control channel without closing first the old one, the UIPC select(2)
loop gets confused and could spin with 100% CPU usage.
Now we check for channels that are reopened, and explicitly close
them before reopening.

Also, fix a check whether a file descriptor is valid: 0 is a valid
file descriptor.
