src: add large page support for macOS

2019-08-20T18:43:47+00:00

Proposal to bring the support for this platform.
We assume the pse36 cpu flag is present for 2MB
large page support present in recent years
in mac line (not to be backported to 10.x anyway).
Recommended better for mac production servers rather
than casual mac books.

build: enable linux large pages LLVM lld linkage support

2019-08-20T04:20:18+00:00

The custom linker script is compatible with GNU ld only.
As such, providin a new expliciting option to redirect to
a different one. lld seems unable to migrate this
large section w/o segfaulting so providing only the
base address anchor for now.

src: readlink("/proc/self/exe") -> uv_exename()

2019-07-30T13:21:06+00:00

This commit also adds error handling. A THP-enabled build terminated
with an out-of-memory error on a system without /proc because it cast
the -1 from readlink() to size_t (i.e. ULONG_MAX) and then tried to
allocate a string of that size.
