Adding previously skipped "readtoken1(pgetc_eatbnl(), syntax_type..." change

parser: use pgetc_eatbnl() in more places
dash has a pgetc_eatbnl function in parser.c which skips any
backslash-newline combinations. It's not used everywhere it could be.
There is also some duplicated backslash-newline handling elsewhere in
parser.c. Replace most of the calls to pgetc() with calls to
pgetc_eatbnl() and remove the duplicated backslash-newline handling.
Testcase:
PS1='\
:::'
should result in ::: prompt, not <newline>::: prompt
