This patch introduces a configuration option USBMSC_WRMULTIPLE,
which is used to store multiple blocks into a larger chunk that
then gets written via the mmcsd_writemultiple() (in case mmcsd
is used).
The bottleneck with the current implementation is the poor
performance due to short block writes. USBMSC_DRVR_WRITE()
always writes only one sector (with eMMC that's usually 512 bytes).
eMMC devices usually erase much larger regions with near constant
time (see Jedec JESD84-B51, Extended CSD register byte [225],
SUPER_PAGE_SIZE): 'This register defines one or multiple of
programmable boundary unit that is programmed at the same time.'
If USBMSC_WRMULTIPLE is defined, then USBMSC_NWRREQS is used to
allocate the write buffer size. We don't want this to be the
default behavior yet as this may reveal unseen bugs in usb drivers
due to the faster overall performance.
Sample configurations with measured performance:
- Without USBMSC_WRMULTIPLE: 470 Kb/s
- With USBMSC_WRMULTIPLE, CONFIG_USBMSC_NWRREQS=4: 1.1 Mb/s
(dd with bs=2k)
- With USBMSC_WRMULTIPLE, CONFIG_USBMSC_NWRREQS=16: 5.2 Mb/s
(dd with bs=8k)
No doubt, this feature alone may make the mass storage work 10
times faster than before with eMMC cards.

1. Fix error recovery mechanism during transmission error
handling (enable transmission at the end).
2. Fix compilation / operation with CONFIG_SAMV7_EMAC_PREALLOCATE=y
3. Enable fully configured address space for transmission queues
to allow sending packets with length more than 976 bytes. With
partially configured address space the AHB error is generated
during transmission of long packets.

With faster data transfer rates, it was seen that the read
requests occasionally were issued while the USB RX operation
was actually in progress. This patch makes sure the system
doesn't accidentally read the RX fifo while it's being filled
up, but rather, checks for the RXCSRL_REG_EPN_RX_PKT_RDY_MASK
flag. This flag indicates the packet is ready to be read.

cache_dbus_mmu_set and cache_ibus_mmu_set return positive values in case
of errors, so DEBUVERIFY could never detect them since this macro checks
for negative values.
Besides, the successful execution of those functions is mandatory for
the reliable operation under Protected Mode, so the verification is
always performed, even when DEBUG is not enabled.

Net poll teardown is not protected by net lock, if the conn is released
before teardown, the assertion failure will be triggered during free dev
callback, this patch will add the net lock around net poll teardown to
fix race condition

Displays with resolution that is not multiplication of 8 had some issues in landscape mode (columns ware shifted).
Fixed function for copying bits.
Optimized memory reload for landscape mode.
When the free connection list is unenough to alloc a new instance,
the TCP stack will reuse the currently closed connection, but if
the handle is not released by the user via close(2), the reference
count of the connection remains in a non-zero value, it will cause
the assertion to fail, so when the handle is not released we should
not use such a conn instance when being actively closed, and ensure
that the reference count is assigned within the net lock protection
