Add and use a common readfile() function
This function is used to read the full content of a textfile into a newly allocated buffer (with zerotermination). It replaces the earlier readfile() in scan-tree.c (which was rather error-prone[1]), and is reused by read_agefile() in ui-repolist.c. 1: No checks for EINTR and EAGAIN, fixed-size buffer Signed-off-by: Lars Hjemli <hjemli@gmail.com>
