6d076caaa6 tools: acrn-crashlog: remove unsafe apis in usercrash
Since strlen/vsnprintf/ato* api are not safe, so use strnlen instead of
strlen, use vasprintf instead of vsnprintf and use strtol instead of
atoi.

6e656dfd3c tools: acrn-crashlog: implementation for the server of usercrash
This patch is the implementation patch for the server of usercrash.

Usercrash works in C/S model: usercrash_s works as usercrash server,
which is to handle events from client in endless loop. Once server
receives dump request from client, it will create usercrash_0x file
under /var/log/usercrashes/ and send file fd to client.
