aeb7ed8c53 syslog/ramlog: initialize g_sysdev based on the current ramlog buffer
by ramlog_initbuf();
Algorithm: Scan the entire ramlog buffer, the position of the head
is the first byte is not empty and second byte is empty. The position
of the tail is the first byte is empty and second byte is not empty.

27835c8c0a ramlog: Add overwrite option to ramlog
Enable overwrite of circular buffer. If RAMLOG buffer overflows,
overwrite it from the top of buffer and always keep the latest log.

a569006fd8 sched/: Make more naming consistent
Rename various functions per the quidelines of https://cwiki.apache.org/confluence/display/NUTTX/Naming+of+OS+Internal+Functions

    nxsem_setprotocol -> nxsem_set_protocol
    nxsem_getprotocol -> nxsem_get_protocol
    nxsem_getvalue -> nxsem_get_value

51a2171c71 ramlog: Remove g_ramlog_syslog_channel since it's same as g_default_channel
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.

dcaaf2d912 ramlog: Remove all ramlog_consoleinit related code
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.

99a501b668 drivers/syslog/ramlog.c: Fix ramlog readers never woken up when using ramlog as syslog or console.
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.

9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

83cdb0c552 Squashed commit of the following:
libc/semaphore:  Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable.  Changed all references to sem_getvalue in the OS to nxsem_getvalue().

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.
