Pattern matching with lists no longer works:
; ls /tmp/*.c
/tmp/npage.c
/tmp/pagedebug.c
/tmp/pageold.c
/tmp/scheduler.c
/tmp/writeimagetest.c
; ls /tmp/^(*.c)
ls: /tmp/*.c: '/tmp/*.c' directory entry not found
; 9fs dump
; bind /n/dump/2021/1002/amd64/bin/rc /bin/rc
; rc
; ls /tmp/^(*.c)
/tmp/npage.c
/tmp/pagedebug.c
/tmp/pageold.c
/tmp/scheduler.c
/tmp/writeimagetest.c
the fix:
we have to propagate the glob attribute thru lists
as well. before it was only handled for single words
and propagated thru concatenations...
the Xglob instruction now works on list, and we
propagate the glob attribute thru PAREN and WORDS
and ARGLIST nodes.
also, avoid using negative numbers for the Tree.glob
field as char might be unsigned on some targets.

Untangle the lexer and interpreter thread state.
Fix the file and line number error reporting, getting rid of
Xsrcfile instruction, as the whole code block can only come
from a single file, stuff the source file in slot[1] of the
code block instead.
Remove limitations for globber (path element limits)
and be more intelligent about handling globbing by
inserting Xglob instruction only when needed and not
run it over every Xsimple argument list.
Remove fragile ndot magic and make it explicit by adding
the -q flag to . builtin command.
Add -b flag for full compilation.
Make exitnext() smart, so we can speculate thru rcmain and
avoid the fork().
Get rid of all print(2) format functions and use io
instead.
Improve the io library, adding rstr() to handle tokenization,
which allows us to look ahead in the already read buffer
for the terminators, avoiding alot of string copies.
Auto indent pcmd(), to make line number reporting more usefull.
Implement here documents properly, so they can work everywhere.

When loading a file using ".", we could
end up with our line numbers thrown off
due to the mutation of lexline. Putting
lexline into the runq beside the file
that we're reading from causes it to get
pushed and popped correctly, so that we
no longer lose track of our location.

This change provides a location for errors
like 'null list in concatenation'.

add glob information to the word structure so we wont accidently
deglob quoted strings containing the GLOB. we store Globsize(word)
in in word->glob which avoids recalculating that values and the
check if a word should be globbed quick.
globlist() now substitutes the word inplace avoiding the copying
when all words are literals and avoids recursion.
minor cleanups: use list2str() in execeval(), move octal() to
unix.c, remove the (char*) casts to efree().

Xqdol() used to take quadratic time because of strcat(),
the code isnt really needed as list2str() aready does the
same thing in linear time without the strcat().
add estrdup() which uses emalloc() so allocation error are
catched.
move strdups() of name from callers into newvar().
avoid recursion of conclist(), and avoid copying of word
strings by providing Newword() function which doesnt copy
the word string.
