liblog: add __android_log_pmsg_file_read (cherry pick from commit 864e8e80e4f6b325ddacc25b0bd5d621eff0fb3a) - This is considered an Android Private function, not exported for general use. - goal is to retreive a file's content from a series of log messages from pmsg, to be retrieved after a reboot for transfer to a persistent location. - files are presented in reverse sorted order, first based on _any_ numerical content, then by alphanumeric order. - Add a gTest for this function, relies on gTest for liblog.__android_log_pmsg_file_write from prior to reboot. Bug: 27176738 Change-Id: If37ef423009bd28b598b233af3bccef3429bdc22

liblog: add __android_log_pmsg_file_write (cherry pick from commit d4b061bde280fce9b5426b5738a02d42ec263c48) - This is considered an Android Private function, not exported for general use. - goal is to record a file's content into a series of log messages into pmsg, to be retrieved after a reboot for transfer to a persistent location. - filename reference is converted to a tag-unique "<dirbase>:<filebase>". - buffer and length representing the filename contents are recorded, along with a sequence number placed into the nsec time field to ANDROID_LOG_PMSG_FILE_MAX_SEQUENCE. - Add a gTest for this function.

logd: Don't embed a flexible array member within another struct C (but not C++) has a concept of a flexible array member, which is documented at https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html . Using a flexible array member indicates that the structure is really a header for a variable length object. In logd's case, the variable length structure android_event_string_t was embedded within another structure called android_log_event_string_t. This makes gcc's __builtin_object_size() function really confused. When compiling with C++, __builtin_object_size(android_log_event_string_t.payload.data, 1) would return 0, whereas if you compiled the code with C, the same call would (properly) return -1. Code which does automatic bounds checking, such as the proposed patch at https://android-review.googlesource.com/145411 , will cause problems for logd if this syntax is used. Don't try to embed a variable length structure within another structure. This doesn't appear to be valid C nor C++, and while it's worked, it seems problematic. Instead, inline the structure so it's one big happy structure. Change-Id: I8ac02b7142a4f6560f5f80df2effcf720f9896fc

logd: create private/android_logger.h - create a structure to depict the private header expected at logd end of socket. - utilize this new structure instead of unscalable byte stream technique used to unpack in logd. Change-Id: I2d0e5c3531c279f2dc1fbd74807210ff8d804de0
