Rewrite `copy_file()` so the lflag and sflag are handled as early as

Currently the data structure holding alias information is opaque for
consumers outside alias.c and there is no way to iterate over all
aliases, which will become needed by a future commit.
The new function "iteralias" takes a null pointer to return the first
alias or an existing alias to return the next one, unless there is
no alias to return, in which case it returns a null pointer.
I slightly changed the static function hashalias so that it returns the
index into the array holding link heads, and not the link head directly.
In this form it's easier to use by iteralias and the slight adjustment
in the three existing callers doesn't look too bad.

using a separate option -D.
The change made in e835ee68e1 did not
follow the convention for relative path symlinks. Per the convention,
paths be prefixed with `${BINDIR}`, not `/bin/`. `${BINDIR}` can be
modified from the Makefile, on the command line, or in the

things.
This follows the convention used in `bin/pkill/Makefile`,

Currently, we handle SIGINT by calling summary() and _exit() directly from the signal handler, which we install after setup(). There are several issues with this:
* summary() is not signal safe;
* the parent is not informed about the signal;
* setup() can block on open(), and catching SIGINT at that stage will produce the correct exit status but will not print anything to stderr as POSIX demands.
Fix this by making SIGINT non-restartable, changing our signal handler to only set a flag, installing it before setup(), and checking the termination flag before and after every blocking operation, i.e. open(), read(), write().
Also add two test cases, one for catching SIGINT while opening the input and one for catching it while reading. I couldn't think of an easy way to test catching SIGINT while writing (it's certainly feasible, but perhaps not from a shell script).

This update implements tallying of free directory entries during
create, delete, or rename operations on FAT12 and FAT16 file systems.
Prior to this change, the total number of root directory entries
was reported as number of inodes, but 0 as the number of free
inodes, causing system health monitoring software to warn about
a suspected disk full issue.
The FAT12 and FAT16 file systems provide a limited number of
root directory entries, e.g. 512 on typical hard disk formats.
The valid range of values is 1 to 65535, but the msdosfs code
will effectively round up "odd" values to the next multiple of 16
(e.g. 513 would allow for 528 root directory entries).
This update implements tracking of directory entries during create,
delete, or rename operations, with initial values determined by
scanning the directory when the file system is mounted.
Total and free directory entries are reported in the f_files and
f_ffree elements of struct statfs, despite differences in semantics
of these values:
- There is no limit on the number of files and directories that can
be created on a FAT file system. Only the root directory of FAT12
and FAT16 file systems is limited, any number of files can still be
created in sub-directories, even when 0 free "inodes" are reported.
- A single file can require 1 to 21 directory entries, depending on
the character set, structure, and length of the name. The DOS 8.3
style file name takes up 1 entry, and if the name does not comply
with the syntax of a DOS 8.3 file name, 1 additional entry is used
for each 13 characters of the file name. Since all these entries
have to be contiguous, it is possible that a file or directory with
a long name can not be created, despite a sufficient total number of
free directory entries.
- Renaming a file can require more directory entries than currently
allocated to store its long name, which may prevent an in-place
update of the name if more entries are needed. This may cause a
rename operation to fail if no contiguous range of free entries for
the new name can be found.
- The volume label is stored in a directory entry. An empty FAT file
system with a volume label will therefore show 1 used "inode" in
df.
- The perceentage of free inodes shown in df or monitoring tools does
only represent the state of the root directory of a FAT12 or FAT16
file system. Neither does a reported value of 0% free inodes does
prevent files from being created in sub-directories, nor does a
value of 50% free inodes guarantee that even a single file with
a "long" name can be created in the root directory (if every other
directory entry is occupied and there are no 2 contiguous entries).
The statfs(2) and df(1) man pages have been updated with a notice
regarding the possibly different semantics of values reported as
total and free inodes for non-Unix file systems.
