Rahul Bedarkar 250b301ceb acl: backport upstream patch to fix static build 
When building tar package with acl in static build configuration, we
get definition clash error for 'quote' function.

../gnu/libgnu.a(quotearg.o): In function 'quote':
quotearg.c:(.text+0x12fc): multiple definition of 'quote'
../sysroot/usr/lib/libacl.a(quote.o):/home/test/autobuild/run/instance-1/output/build/acl-2.2.52/libmisc/quote.c:27: first defined here

In acl upstream, this is already fixed by renaming quote and unquote
internal functions. This commit backports upstream patch.

Fixes:

Subject: [PATCH] add __acl_ prefixes to internal symbols
When static linking libacl, people sometimes run into symbol collisions
because their own code defines symbols like "quote". So for acl internal
symbols, use an __acl_ prefix.
