Add basic sample rate conversion to the CXD56 Spresense audio
driver using libsamplerate. Currently conversion is only done
during playback and all output is fixed at 48 kHz.
Issues:
- 16 kHz SRC has glitches (unless data dump is enabled)
- 44.1 kHz SRC gets stuck

1.use userspace buffer rather than intermediate buffer of upperhalf driver
2.support block and non-block ways.

1.support for multi-user access
2.support special cmd to control sensor
3.support userspace to set size of intermediate buffer

When audio fails it is usefull to have I2S transfer errors in place
to be able to track the issue

This adds the inital wiring for i2c bus support in the sim target
and for Linux host adds the lower half that uses the i2c chardev.

Summary:
- This commit enables gs2200m driver to get IWNWID/IWFREQ/IWSENS information
Impact:
- Affects gs2200m only
Testing:
- Tested with spresense:wifi
The sendblk function was missing NOSTOP on the first msg of the
i2c transaction. This could cause an extra STOP to be inserted
in the transaction.
The driver uses up_mdelay for some timing where it should be
using a sleep.

Summary:
- This commit enables gs2200m driver re-associate to the access point when disassociated
Impact:
- Affects gs2200m only
Testing:
- Tested with spresense:wifi
Follow the POSIX description.
SIGTSTP should be sent when the Ctrl-Z characters is encountered, not SIGSTP.
Testing:
Built with hifive1-revb:nsh (CONFIG_SERIAL_TERMIOS=y, CONFIG_SIG_DEFAULT=y and CONFIG_TTY_SIGTSTP=y)
Summary:
- During network stress testing, ASSERT happened in gs2200m_ioctl_connect()
- The test was nxplayer (http audio streaming) and repeating wget every 0.5sec
- gs2200m_ioctl_connect() calls gs2200m_send_cmd() to send an AT command
- Then it waits for a synchronous command response.
- However, if heavy tcp traffic happens on another socket, it can receive a bulk packet
- With this commit, if it receives such a packet then the packet is duplicated.
- After that, the duplicated packet is added to the packet queue and notify the userland.
Impact:
- Affect almost all use cases with gs2200m
Testing:
- Tested with both spresense:wifi and spresense:wifi_smp
- Tested with nxplayer (http audio streaming) and repeat wget

There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!
