Variants of local:<path> that are used to access other Android

-log:<name>
- Opens one of the system logs (/dev/log/<name>) and allows the client

+DESCRIPTION
+ liblog represents an interface to the volatile Android Logging system
+ for NDK (Native) applications and libraries. Interfaces for either
+ writing or reading logs. The log buffers are divided up in Main, Sys‐
+ tem, Radio and Events sub-logs.
+
+ The logging interfaces are a series of macros, all of which can be
+ overridden individually in order to control the verbosity of the appli‐
+ cation or library. [ASR]LOG[VDIWE] calls are used to log to BAsic,
+ System or Radio sub-logs in either the Verbose, Debug, Info, Warning or
+ Error priorities. [ASR]LOG[VDIWE]_IF calls are used to perform thus
+ based on a condition being true. IF_ALOG[VDIWE] calls are true if the
+ current LOG_TAG is enabled at the specified priority. LOG_ALWAYS_FATAL
+ is used to ALOG a message, then kill the process. LOG_FATAL call is a
+ variant of LOG_ALWAYS_FATAL, only enabled in engineering, and not
+ release builds. ALOG_ASSERT is used to ALOG a message if the condition
+ is false; the condition is part of the logged message.
+ LOG_EVENT_(INT|LONG) is used to drop binary content into the Events
+ sub-log.
+
+ The log reading interfaces permit opening the logs either singly or
+ multiply, retrieving a log entry at a time in time sorted order,
+ optionally limited to a specific pid and tail of the log(s) and finally
+ a call closing the logs. A single log can be opened with android_log‐
+ ger_list_open; or multiple logs can be opened with android_log‐
+ ger_list_alloc, calling in turn the android_logger_open for each log
+ id. Each entry can be retrieved with android_logger_list_read. The
+ log(s) can be closed with android_logger_list_free. The logs should be
+ opened with an O_RDONLY mode. O_NDELAY mode will report when the log
+ reading is done with an EAGAIN error return code, otherwise the
+ android_logger_list_read call will block for new entries.
+
+ The value returned by android_logger_open can be used as a parameter to
+ the android_logger_clear function to empty the sub-log. It is recom‐
+ mended to only open log O_WRONLY.
+
+ The value returned by android_logger_open can be used as a parameter to
+ the android_logger_get_log_(size|readable_size|version) to retrieve the
+ sub-log maximum size, readable size and log buffer format protocol ver‐
+ sion respectively. android_logger_get_id returns the id that was used
+ when opening the sub-log. It is recommended to open the log O_RDONLY
+ in these cases.
