Reason:
nx_start use syslog at every early time event the idle thread not
full setup, then syslog_rpmsg -> work_queue -> work_signal ->
nxsig_kill -> rtcb is NULL -> crash
Fix:
sched work_queue after is_rpmsg_ept_ready() is true

Same as syslog/Make.defs to use #ifdef CONFIG_SYSLOG_RPMSG to build syslog_rpmsg.c
in which syslog_rpmsg_init defined.

And remove syslog_init_e because all initialization is later now and we don't
distinguish the initialition phase anymore after ramlog don't need special
initialize.
Because we can get the same function by CONSOLE_SYSLOG/syslog_console_init.
BTW, it isn't a good choice to use g_ramlogfops as /dev/console since nsh
will read back what it send out which will surprise most people.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
We also make an attempt to avoid the thundering herd problem if there are multiple readers/pollers.
Patch also removes forcing CONFIG_RAMLOG_CRLF in nuttx/syslog/ramlog.h as there is no point of wasting precious RAM for useless characters.
This port was effort of a number of people, I rather arbitrarily gave authorship to Guiding Li because he has the largest number of fundamental quashed commits from the Xiamoi repository.
Squashed commit of the following:
Author: Xiang Xiao <xiaoxiang@pinecone.net>
include/nuttx/b2c.h and libx/libc/string: Add non-standard string functions to deal with cases where there are more than 8-bits in a type char.
Author: Gregory Nutt <gnutt@nuttx.org>
Fix several build issues/missing definitiona needed for OpenAMP build in drivers/.
Add OpenAMP code has been reviewed and ran through tools/nxstyle (with all reports accounted for).
Author: Xiang Xiao <xiaoxiang@xiaomi.com>
tools/: Fix the minor issue in Makefile
Author: Gregory Nutt <gnutt@nuttx.org>
drivers/rptun/rptun.c: Review for coding standard. Run against tools/nxstyle.
tools/LibTargets.mk: Fix some TABs that were turned into spaces by a copy-paste.
fs/hostfs: Add configure and build support for hostfs RPC.
drivers/timer: Add configure and build support for syslog RTC.
drivers/syslog: Add configure and build support for syslog RPC.
drivers/serial: Add configure and build support for serial RPC.
Kconfig, tools/*.mk. openamp/: Add basic OpenAMP build support.
drivers/rptun: Add configure and build support for OpenAMP tunnel drivers.
drivers/net: Update Make.defs and Kconfig for OpenSDA support.
Remove drivers/clk/clk-rpmsg.c drivers/power/rpmsg_regulator.c. These depend on upstreaming support for a new subsystem based on the clk/regulator is model from Linux. Removed because we want to separate the activities. We will just try to get the basic OpenAMP support in place for now.
Remove drivers/misc/misc_rpmsg.c and include/nuttx/misc/misc_rpmsg.h. These are specific to the Xiaomi application.

Iobinstrumentation
* mm/iob: Introduces producer/consumer id to every iob call. This is so that the calls can be instrumented to monitor the IOB resources.
* iob instrumentation - Merges producer/consumer enumeration for simpler IOB user.
* fs/procfs: Starts adding support for /proc/iobinfo
* fs/procfs: Finishes first pass of simple IOB user stastics and /proc/iobinfo entry
