client_send_listener: send correct peerid fix typo in previous commit where `0' was used instead of peerid. Spotted by cage, thanks!

add IMSG_CTL_DEBUG to debug the opened fid meant to be used from kamictl to dump all the opened fid by every connection.

listener: handle IMSG_CTL_LOG_VERBOSE adjust the logging level and forward it to every client process so they can do so too.

wstat: missing read for size 9p stat message have a leading 2 bytes long size field. It's meant to simplify the parsing, because while reading the contents of a directory it's necessary to know how much long an entry is, so the length field is present even in the Rstat reply and in the Twstat input. Previously we didn't consume that bit and thus mis-read all of the following fields.

kamid: simplify "not a directory" check

work around wstat limitation the previous commit added an explicit check for extra data in messages. The problem is that wstat voluntarily skips reading some fields at the end, so the len will always be greater than zero!

fail if the received packet is too long This adds extra checks to every t* function: if the client sent too much data per message, treat is an a protocol violation and terminate the connection. Regress suite still passes, this is just an extra safety check for finding wrong clients implementations. The twrite function was the only one with a check like this.

fix np_read{8,16,32,64} functions they should return 0 on failure, not -1

kamid: change fid fname size to NAME_MAX the fname field is just the file name, so NAME_MAX is more appropriate. Committing this separately from the rename change so it's easier to roll back eventually.

kamid: rename field fpath to fname it's actually just the file name, not a path

kamid: add wstat it's not exactly compliant, as 9p requires the changes to be done atomically, but it's not possible to better targeting a UNIX file system. The 9p manpage regarding wstat isn't clear about the behaviour when changing the name of the file: kamid changes the associated fid to reflect the rename. kamid also allows to rename files to other directories, the fid is updated to the new location even in this case.

the reported length for directories must be zero plan9' stat(3) says so...

simplify client proc bootstrap Drop the IMSG_AUTH_DIR imsg type and stuff everything in a struct kd_auth_proc that gets sent via IMSG_AUTH. Tweak the necessary bits to compile. While here also start documenting what data we send over which imsg. As an added benefit, now we're sending fixed-size messages instead of variable length strings.

Merge branch 'portable' Trying to maintain two branches was impossible at this stage for me alone, so I'll recognize my stupidity and merge the portable branch into the main one. The repository will build using autotools.
